Abstract

A static random access memory (SRAM) device includes a memory array of a plurality of memory cells, a controller that receives an external clock signal formed by a succession of external pulses and generates an internal clock signal formed by a succession of internal pulses, and a driving circuit that receives the internal clock signal. The controller is operable in a first mode, wherein the controller generates, for each external pulse, a corresponding internal pulse and the controller controls the driving circuit so that the driving circuitry carries out one access to the memory array for each internal pulse. The controller is further operable in a second mode, wherein the controller generates, for each external pulse, a pair of internal pulses, and the controller controls the driving circuitry so that, for each pair of internal pulses, the driving circuitry writes a first data item in a set of memory cells, and then reads the set of memory cells, so as to acquire a second data item.
