DESCRIPTION
The Simtek STK14C88-3 is a fast static RAM with a
nonvolatile element incorporated in each static
memory cell. The SRAM can be read and written an
unlimited number of times, while independent, non-
volatile data resides in nonvolatile elements. Data
transfers from the SRAM to the nonvolatile elements
(the STORE operation) can take place automatically
on power down. A 68
F or larger capacitor tied from
V
CAP to ground guarantees the STORE operation,
regardless of power-down slew rate or loss of power
from “hot swapping”. Transfers from the nonvolatile
elements to the SRAM (the RECALL operation) take
place automatically on restoration of power. Initia-
tion of STORE and RECALL cycles can also be soft-
ware
controlled
by
entering
specific
read
sequences. A hardware STORE may be initiated with
the HSB pin.
