Data-Retention Mode
MHS CMOS RAMs are designed with battery backup in
mind. Data retention voltage and supply current are
guaranteed over temperature. The following rules insure
data retention :
1 – Chip select (CS) must be held high during data
retention ; within Vcc to VCC
DR
.
2 – CS must be kept between V
CC
– 0.2 V and 70 % of Vcc
during the power up and power down transitions.
3 – The RAM can begin operation > tRC after Vcc
reaches the minimum operating voltage (3 volts).
