The present invention belongs to the field of integrated circuit technology, and is especially one kind of current mode sense amplifier for embedded SRAM. The current mode sense amplifier consists of mainly bit line clamp circuit, cross coupling inverter, equalizing circuit and I/O buffer. The sense amplifier can realize both the read operation and the write operation on SRAM unit by means of the differential current signal, rather than traditional differential voltage signal, resulting in very small bit line voltage swing and effectively lowered memory read/write power consumption. Simulation result shows that the sense amplifier has delay insensitive on capacitance variance.
