DESCRIPTION
The Simtek STK10C48 is a fast static RAM with a non-
volatile element incorporated in each static memory
cell. The SRAM can be read and written an unlimited
number of times, while independent nonvolatile data
resides in the Nonvolatile Elements. Data may easily
be transferred from the SRAM to the Nonvolatile Ele-
ments (the STORE operation), or from the Nonvolatile
Elements to the SRAM (the RECALL operation), using
the NE pin. Transfers from the Nonvolatile Elements to
the SRAM (the RECALL operation) also take place auto-
matically on restoration of power. The STK10C48
combines the high performance and ease of use of a
fast SRAM with nonvolatile data integrity.
The STK10C48 features industry-standard pinout for
nonvolatile RAMs.
