1. An apparatus comprising:
an array of static random-access memory (SRAM) cells, wherein each SRAM cell of the array has a size within a target range,
wherein each SRAM cell of the array of SRAM cells is configured to be initialized to a corresponding initial state based on
a supply voltage received during a power-up operation of the array; and
circuitry configured to initiate a corrective action related to the array, the corrective action based on a number of the
SRAM cells of the array of SRAM cells that, responsive to the power-up operation, have a particular initial state.
