chip-enable input

A control input that, when active, permits operation of the integrated circuit and, when inactive, causes the integrated circuit to be in a reduced-power standby mode. (Ref. IEC 748‑2.)

NOTE A chip-enable input is a clock or strobe input that significantly affects the power dissipation of the integrated circuit. For example, it may be the cycle control input of a dynamic memory or a power-reduction input of a static memory.
