Power-down Mode for Micropower SRAMs
What is automatic power-down mode?
When the chip is deselected (i.e. /CE de-asserted) and no inputs are toggling, the device powers itself down except for the internal memory array. This results in a lesser power dissipation in this mode. This mode is called power-down mode.
