Abstract:
A Random Access Memory (RAM) and method of using the same are disclosed. The RAM includes a plurality of memory cells arranged in columns and in rows with each memory cell coupled to at least one word line and at least one bit line. The RAM includes a plurality of switches with at least one of the switches coupled between two of the memory cells to allow data to be copied from one of the two memory cells to the other of the two memory cells. In another aspect, the two memory cells can be considered a dual bit cell that contains a copying mechanism. There are two interleaved memory planes, assembled from bit cells that contain two bits of information. One bit is the primary bit that corresponds to the normal RAM bit. The second bit is able to receive a copy and hold the primary value. When the copying mechanism is over, the two memory planes may act as two completely independent structures.
