چکیده
Performance of sense amplifier has considerable impact on the speed of caches used in microprocessors. The small difference in voltage level of bit lines of memory cell is amplified by sense amplifier. voltage mode sense amplifier reduces the power dissipation during read and increases the speed also. This paper describes voltage mode sense amplifier and current mode sense amplifier and compare their power dissipation and time delay. current sense amplifier is independent of bit line capacitance and it ia better choice in high density RAM. Delay of voltage mode increases with bit line capacitance.so it is a better choice.

متن کاملImplementation of Latch Type Sense Amplifier
Sense amplifiers plays an important role in memories like Dynamic Random Access (DRAM) and Static Random Access (SRAM) for read and write operations. A sense amplifier compares the bit line voltage and its complement amplifies it to rail to rail output voltages. In this project, we mainly concentrated on the write operation. Sense amplifier is one of the peripheral circuits in memories that are...
