The proposed SRAM has three modes: a typical mode, high-speed mode, and dependable mode, in which the QoB is scalable. That is, the area, speed, reliability, and/or power of one-bit information can be controlled. In the typical mode, assignment of information is as usual as one memory cell has one bit. On the other hand, in the high-speed or dependable mode, one-bit information is stored in two memory cells, which boosts the speed or increases the reliability. In the high speed mode, the cell current is increased by 142％, and bitline discharge time is reduced by 66.3％. Furthermore, in dependable mode, Bit error rate (BER) in proposed SRAM is improved by 2.5x10-2.
