GENERAL DESCRIPTION
The HMN1288J Nonvolatile SRAM is a 1,048,576-bit static RAM organized as 131,072 bytes by 8 bits.
The HMN1288J has a self-contained lithium energy source provide reliable non-volatility coupled with the unlimited write
cycles of standard SRAM and integral control circuitry which constantly monitors the single 5V supply for an out-of-
tolerance condition. When such a condition occurs, the lithium energy source is automatically switched on to sustain the
memory until after Vcc
returns valid and write protection is unconditionally enabled to prevent garbled data. In addition the
SRAM is unconditionally write-protected to prevent an inadvertent write operation. At this time the integral energy source is
switched on to sustain the memory until after V
CC
returns valid.
The HMN1288J uses extremely low standby current CMOS SRAM
s, coupled with small lithium coin cells to provide non-
volatility without long write-cycle times and the write-cycle limitations associated with EEPROM.
