ABSTRACT:
A sequential access memory working at the rate of a clock signal CK includes N register elements N, each storing an information bit. These register elements are divided into L groups, each comprising P elements that are series-connected and simultaneously activated or not activated (with P.times.L=N). The register elements of a given group are activated at least P times consecutively during a part of the time, and are not activated for the rest of the time. Accordingly, each group stores P consecutive information bits each from among the N bits arriving in serial form at the input of the memory. The advantage of the memory is that it enables a reduction in the dynamic energy consumption.
