Abstract:
An integrated circuit for storing data comprises a memory cell array comprising a plurality of bit cells (BC1, . . . , BCn) comprising a first and a second one of the bit cells (BC1, BC2) having a static random access memory architecture. The first and the second bit cells (BC1, BC2) are coupled to a common wordline (WL_TOP) and are arranged in different columns (C1, C2) of the memory cell array (100). During a write access to the first bit cell (BC1), the first bit cell (BC1) undergoes a write operation, whereas the second bit cell (BC2) is a half-selected bit cell which undergoes a pseudo read operation. The integrated circuit uses a two-phase write scheme to improve the write-ability in low operating voltage environment.
