SERIAL SRAM COMMANDS
Write to SRAM Command (72H)
The Write to SRAM command (72H) provides access to
the 264-Byte SRAM independently of any Flash memory
array operation. When CS is asserted high to complete
the command, the contents of the SRAM will be main-
tained until overwritten through another command or the
power is removed. Using the Write to SRAM command,
1
data can be loaded in preparation of writing to a sector in
memory and then transferred to a selected sector using
the Transfer SRAM to Sector command. The TR bit in the
2 status register should be checked first if Transfer Sector to
SRAM or Compare Sector to SRAM commands are used.

Read from SRAM (71H)
The Read from SRAM command (71H) provides access to
the 264-Byte SRAM independent of any Flash memory
array operations. The TR bit in the status register should be
checked first if Transfer Sector to SRAM or Compare Sector
to SRAM commands are used.
