Review of Flip-Flop Based on Sense Amplifier for Memory Read Operation

Day by day increase in demand high speed and low power portable embedded circuit is evolved in many variants. Sense amplifier accepts small voltage difference as input and generate full swing output depends on BL/BLB data. Technology scaling has enabled us to integrate both memory and logic circuits on a single chip. However, the performance of embedded memory and its peripheral circuits can adversely affect the speed and power of the overall system. Sense amplifier is one of the important peripheral circuits in the memory as it strongly influences the memory access times. It retrieves the stored data from the memory array by amplifying the small differential signal on the bit lines. Therefore, the total power dissipated within the on-chip caches, include both on-time and standby will become dominant parts of the total power consumption of the chip. In view of the above, there apparent urgency to address the power dissipation of chip. Similarly sensing speed and Qvalue also considered for fair review.
