Abstract

A sensor circuit is used to provide bit-cell read strength distribution of an SRAM array. A current-mirror circuit mirroring the bit-line current of an SRAM array is used to power the sensor circuit. A reference current representing nominal bit-cell read current is used as a reference. The current-mirror circuit senses the bit-line current. The current-mirror and the ring oscillator are not part of the bit-line read path.
