Functional Description  
20 ns, 25 ns, and 45 ns Access Times  
The Cypress CY14B101LA/CY14B101NA is a fast static RAM,  
with a nonvolatile element in each memory cell. The memory is  
Internally organized as 128K x 8 (CY14B101LA) or 64K x 16  
organized as 128K bytes of 8 bits each or 64K words of 16 bits  
each. The embedded nonvolatile elements incorporate  
QuantumTrap technology, producing the world’s most reliable  
nonvolatile memory. The SRAM provides infinite read and write  
cycles, while independent nonvolatile data resides in the highly  
reliable QuantumTrap cell. Data transfers from the SRAM to the  
nonvolatile elements (the STORE operation) takes place  
automatically at power down. On power up, data is restored to  
the SRAM (the RECALL operation) from the nonvolatile memory.  
Both the STORE and RECALL operations are also available  
under software control.

Device Operation  
CAP  
The CY14B101LA/CY14B101NA nvSRAM is made up of two  
functional components paired in the same physical cell. They are  
an SRAM memory cell and a nonvolatile QuantumTrap cell. The  
SRAM memory cell operates as a standard fast static RAM. Data  
in the SRAM is transferred to the nonvolatile cell (the STORE  
operation), or from the nonvolatile cell to the SRAM (the RECALL  
operation). Using this unique architecture, all cells are stored and  
recalled in parallel. During the STORE and RECALL operations,  
SRAM read and write operations are inhibited. The  
CY14B101LA/CY14B101NA supports infinite reads and writes  
similar to a typical SRAM. In addition, it provides infinite RECALL  
operations from the nonvolatile cells and up to 200K STORE  
operations. Refer to the Truth Table For SRAM Operations on  
page 15 for a complete description of read and write modes.  
CAP  
pin is driven to V by a regulator on the chip. Place a  
CAP  
CC  
pull up on WE to hold it inactive during power up. This pull up is  
only effective if the WE signal is tri-state during power up. Many  
MPUs tri-state their controls on power up. This must be verified  
when using the pull up. When the nvSRAM comes out of  
power-on-recall, the MPU must be active or the WE held inactive  
until the MPU comes out of reset.  
To reduce unnecessary nonvolatile stores, AutoStore and  
Hardware STORE operations are ignored unless at least one  
write operation has taken place since the most recent STORE or  
RECALL cycle. Software initiated STORE cycles are performed  
regardless of whether a write operation has taken place. The  
HSB signal is monitored by the system to detect if an AutoStore  
cycle is in progress.  
SRAM Read  
Figure 4. AutoStore Mode  
The CY14B101LA/CY14B101NA performs a read cycle when  
CE and OE are LOW and WE and HSB are HIGH. The address

output, in the case of 16-bit words. When the read is initiated by  
0.1uF

The CY14B101LA/CY14B101NA provides the HSB pin to

AutoStore Operation  
The CY14B101LA/CY14B101NA stores data to the nvSRAM  
using one of the following three storage operations: Hardware  
STORE activated by HSB; Software STORE activated by an  
address sequence; AutoStore on device power down. The  
AutoStore operation is a unique feature of QuantumTrap  
SRAM read and write operations that are in progress when HSB  
is driven LOW by any means are given time to complete before  
the STORE operation is initiated. After HSB goes LOW, the  
CY14B101LA/CY14B101NA continues SRAM operations for

CY14B101LA, CY14B101NA

The software sequence may be clocked with CE controlled reads  
or OE controlled reads. After the sixth address in the sequence

Data is transferred from nonvolatile memory to the SRAM by a

HRECALL  
Software STORE  
Data is transferred from SRAM to the nonvolatile memory by a  
software address sequence. The CY14B101LA/CY14B101NA  
Software STORE cycle is initiated by executing sequential CE  
controlled read cycles from six specific address locations in  
exact order. During the STORE cycle an erase of the previous  
nonvolatile data is first performed, followed by a program of the  
nonvolatile elements. After a STORE cycle is initiated, further  
input and output are disabled until the cycle is completed.

2. Read Address 0xB1C7 Valid READ  
3. Read Address 0x83E0 Valid READ  
4. Read Address 0x7C1F Valid READ  
5. Read Address 0x703F Valid READ  
6. Read Address 0x4C63 Initiate RECALL Cycle  
Because a sequence of READs from specific addresses is used  
for STORE initiation, it is important that no other read or write  
accesses intervene in the sequence, or the sequence is aborted  
and no STORE or RECALL takes place.  
Internally, RECALL is a two step procedure. First, the SRAM data  
is cleared. Next, the nonvolatile information is transferred into the  
SRAM cells. After the t  
cycle time, the SRAM is again  
RECALL  
ready for read and write operations. The RECALL operation  
does not alter the data in the nonvolatile elements.  
To initiate the Software STORE cycle, the following read  
sequence must be performed:  
1. Read Address 0x4E38 Valid READ  
2. Read Address 0xB1C7 Valid READ  
3. Read Address 0x83E0 Valid READ

Preventing AutoStore  
Data Protection  
The AutoStore function is disabled by initiating an AutoStore  
disable sequence. A sequence of read operations is performed  
in a manner similar to the Software STORE initiation. To initiate  
the AutoStore disable sequence, the following sequence of CE  
controlled read operations must be performed:  
The CY14B101LA/CY14B101NA protects data from corruption  
during low voltage conditions by inhibiting all externally initiated  
STORE and write operations. The low voltage condition is  
detected when  
V
is less than  
V
.
If the  
CC  
SWITCH  
CY14B101LA/CY14B101NA is in a write mode (both CE and WE  
are LOW) at power up, after a RECALL or STORE, the write is  
1. Read address 0x4E38 Valid READ  
2. Read address 0xB1C7 Valid READ  
3. Read address 0x83E0 Valid READ  
4. Read address 0x7C1F Valid READ  
5. Read address 0x703F Valid READ  
6. Read address 0x8B45 AutoStore Disable  
inhibited until the SRAM is enabled after t  
(HSB to output  
LZHSB  
active). This protects against inadvertent writes during power up  
or brown out conditions.  
Noise Considerations  
The AutoStore is reenabled by initiating an AutoStore enable  
sequence. A sequence of read operations is performed in a  
manner similar to the Software RECALL initiation. To initiate the  
AutoStore enable sequence, the following sequence of CE  
controlled read operations must be performed:  
1. Read address 0x4E38 Valid READ  
2. Read address 0xB1C7 Valid READ  
3. Read address 0x83E0 Valid READ  
4. Read address 0x7C1F Valid READ  
5. Read address 0x703F Valid READ  
6. Read address 0x4B46 AutoStore Enable  
If the AutoStore function is disabled or reenabled, a manual  
STORE operation (Hardware or Software) must be issued to  
save the AutoStore state through subsequent power down  
cycles. The part comes from the factory with AutoStore enabled.

29. This is the amount of time it takes to take action on a soft sequence command. Vcc power must remain HIGH to effectively register command.  
30. Commands such as STORE and RECALL lock out IO until operation is complete which further increases this time. See the specific command.
