The Cypress CY14E104L/CY14E104N is a fast static RAM with
a nonvolatile element in each memory cell. The memory is
organized as 512K words of 8 bits each or 256K 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 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.

CY14E104L/CY14E104N
PRELIMINARY
The CY14E104L/CY14E104N 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,
the SRAM read and write operations are inhibited. The
CY14E104L/CY14E104N 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.
SRAM Read
The CY14E104L/CY14E104N performs a read cycle when CE
and OE are LOW and WE and HSB are HIGH. The address
specified on pins A0-18 or A0-17 determines which of the 524,288
data bytes or 262,144 words of 16 bits each are accessed. When
the read is initiated by an address transition, the outputs are valid
after a delay of tAA (read cycle #1). If the read is initiated by CE
or OE, the outputs are valid at tACE or at tDOE, whichever is later
(read cycle #2). The data output repeatedly responds to address
changes within the tAA access time without the need for transitions on any control input pins. This remains valid until another
address change or until CE or OE is brought HIGH, or WE or
HSB is brought LOW.
SRAM Write
A write cycle is performed when CE and WE are LOW and HSB
is HIGH. The address inputs must be stable before entering the
write cycle and must remain stable until CE or WE goes HIGH at
the end of the cycle. The data on the common IO pins DQ0-15 are
written into the memory if the data is valid tSD before the end of
a WE controlled write or before the end of an CE controlled write.
It is recommended that OE be kept HIGH during the entire write
cycle to avoid data bus contention on common IO lines. If OE is
left LOW, internal circuitry turns off the output buffers tHZWE after
WE goes LOW.
AutoStore Operation
The CY14E104L/CY14E104N 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 activated on device power down. The
AutoStore operation is a unique feature of QuantumTrap
technology
and
is
enabled
by
default
on
the
CY14E104L/CY14E104N.
During a normal operation, the device draws current from VCC to
charge a capacitor connected to the VCAP pin. This stored
charge is used by the chip to perform a single STORE operation.
If the voltage on the VCC pin drops below VSWITCH, which is
below the minimum specified operating voltage, the part
automatically disconnects the VCAP pin from VCC. A STORE
operation is initiated with power provided by the VCAP capacitor.

Figure 4 shows the proper connection of the storage capacitor
(VCAP) for automatic store operation. Refer to DC Electrical
Characteristics on page 7 for the size of VCAP.
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.
Hardware STORE (HSB) Operation
The CY14E104L/CY14E104N provides the HSB pin to control
and acknowledge the STORE operations. The HSB pin is used
to request a hardware STORE cycle. When the HSB pin is driven
LOW, the CY14E104L/CY14E104N conditionally initiates a
STORE operation after tDELAY. An actual STORE cycle begins
only if a write to the SRAM has taken place since the last STORE
or RECALL cycle. The HSB pin also acts as an open drain driver
that is internally driven LOW to indicate a busy condition when
the STORE (initiated by any means) is in progress.
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
CY14E104L/CY14E104N continues SRAM operations for
tDELAY. During tDELAY, multiple SRAM read operations may take
place. If a write is in progress when HSB is pulled LOW it is
allowed a time, tDELAY, to complete. However, any SRAM write
cycles requested after HSB goes LOW are inhibited until HSB
returns HIGH.
During any STORE operation, regardless of how it is initiated,
the CY14E104L/CY14E104N continues to drive the HSB pin
LOW, releasing it only when the STORE is complete. Upon
completion
of
the
STORE
operation,
the
CY14E104L/CY14E104N remains disabled until the HSB pin
returns HIGH. Leave the HSB unconnected if it is not used.

PRELIMINARY
Hardware RECALL (Power Up)
The software sequence may be clocked with CE controlled reads
or OE controlled reads. After the sixth address in the sequence
is entered, the STORE cycle commences and the chip is
disabled. It is important to use read cycles and not write cycles
in the sequence, although it is not necessary that OE be LOW
for a valid sequence. After the tSTORE cycle time is fulfilled, the
SRAM is activated again for a read and write operation.
During power up or after any low power condition (VCC <
VSWITCH), an internal RECALL request is latched. When VCC
exceeds the sense voltage of VSWITCH, a RECALL cycle is
automatically initiated and takes tHRECALL to complete.
Software STORE
Software RECALL
Data is transferred from the SRAM to the nonvolatile memory by
a software address sequence. The CY14E104L/CY14E104N
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.
Data is transferred from the nonvolatile memory to the SRAM by
a software address sequence. A software RECALL cycle is
initiated with a sequence of read operations in a manner similar
to the software STORE initiation. To initiate the RECALL cycle,
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 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.
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
4. Read address 0x7C1F Valid READ
5. Read address 0x703F Valid READ
6. Read address 0x8FC0 Initiate STORE cycle
Internally, RECALL is a two step procedure. First, the SRAM data
is cleared; then, the nonvolatile information is transferred into the
SRAM cells. After the tRECALL cycle time, the SRAM is again
ready for read and write operations. The RECALL operation
does not alter the data in the nonvolatile elements.

Preventing AutoStore
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:
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
The AutoStore is re-enabled 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
Document Number: 001-09603 Rev. *H
If the AutoStore function is disabled or re-enabled, 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.
Data Protection
The CY14E104L/CY14E104N protects data from corruption
during low voltage conditions by inhibiting all externally initiated
STORE and write operations. The low voltage condition is
detected when VCC < VSWITCH. If the CY14E104L/ CY14E104N
is in a write mode (both CE and WE are LOW) at power up, after
a RECALL or STORE, the write is inhibited until a negative
transition on CE or WE is detected. This protects against
inadvertent writes during power up or brown out conditions.
Noise Considerations
Refer CY application note AN1064.

Notes
17. The software sequence is clocked with CE controlled or OE controlled reads.
18. The six consecutive addresses must be read in the order listed in the Table 1 on page 5. WE must be HIGH during all six consecutive cycles.
19. 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.
20. Commands such as STORE and RECALL lock out IO until operation is complete which further increases this time. See the specific command.
21. On a hardware STORE initiation, SRAM operation continues to be enabled for time tDELAY to allow read and write cycles to complete.
