Features Functional Description
25 ns and 45 ns access times The Cypress CY14V104LA/CY14V104NA is a fast static RAM,
with a non-volatile element in each memory cell. The memory is
Internally organized as 512 K 8 (CY14V104LA) or 256 K 16
organized as 512 K bytes of 8 bits each or 256 K words of 16 bits
(CY14V104NA)
each. The embedded non-volatile elements incorporate
QuantumTrap technology, producing the worlds most reliable
Hands off automatic STORE on power-down with only a small
non-volatile memory. The SRAM provides infinite read and write
capacitor
cycles, while independent non-volatile data resides in the highly
STORE to QuantumTrap non-volatile elements initiated by
reliable QuantumTrap cell. Data transfers from the SRAM to the
software, device pin, or AutoStore on power-down
non-volatile elements (the STORE operation) takes place
automatically at power-down. On power-up, data is restored to
RECALL to SRAM initiated by software or power-up
the SRAM (the RECALL operation) from the non-volatile
Infinite read, write, and recall cycles memory. Both the STORE and RECALL operations are also
available under software control.
1-million STORE cycles to QuantumTrap
