A static random access memory device includes a memory matrix provided with at least one set of SRAM memory cells and a circuit for initializing cells of the set, the setting circuit being able to carry out various setting types and in particular a 'deterministic' setting in which the cells are established at an imposed value and to carry out a “free” setting in which the cells are established at a value that depends on their manufacturing method.

SRAM with reconfigurable setting

Electronic component including a ternary content-addressable memory component, configured to compare the input data items with a set of pre-recorded reference data words; the memory component incorporates a matrix of elementary cells arranged in lines and columns; each line incorporates cells in each of which is recorded one bit of one of the reference data words; the cells of a given column are dedicated to the comparison of the same bit of the input data word; each cell incorporates: two memory points storing the data representing the reference data bit; a comparison circuit connected to the memory points, with a comparison point of which the potential represents the comparison if the input data bit and the data stored in the memory points, and also incorporating a common comparison circuit to which are connected the comparison circuits of all or part of the cells of a given column; the comparison circuit incorporates terminals to which the bit from the input data word and its complement are applied.
