DESCRIPTION
The Simtek STK11C48 is a fast static
nonvolatile element incorporated in each static
memory cell. The
unlimited number of times, while independent, non-
volatile data resides in the Nonvolatile Elements.
Data transfers from the
ments (the
Elements to
place using a software sequence. Transfers from the
Nonvolatile Elements to the
operation) also take place automatically on restora-
tion of power.

... The STK11C48 is a versatile memory chip that pro- vides several modes of operation. The STK11C48 can operate as a standard Nonvolatile Elements shadow to which the information can be copied or from which the SRAM can be updated in nonvolatile mode. SRAM NOISE CONSIDERATIONS Note that the STK11C48 is a high-speed memory and so must have a high-frequency bypass capaci- tor of approximately 0.1μ ...
