Abstract:
A memory device and a method for test reading and writing thereof are provided. A precharge voltage control circuit is based on the precharge reference voltage to provide a first precharge voltage and a second precharge voltage. A sense amplifier circuit is coupled between a bit line and a complementary bit line and configured to sense data of a memory cell coupled to the bit line, and also coupled to the precharge voltage control circuit to make the bit line and the complementary bit line receive the first precharge voltage and the second precharge voltage respectively, the first precharge voltage and the second precharge voltage are on the same voltage level during the precharge operation, but during a test write sensing period and a test read sensing period after the precharge operation, the voltage levels of the first precharge voltage and the second precharge voltage are different.

Claim (Index 4):
The memory device according to  claim 2 , further comprising:\n a precharge enable control circuit, coupled to the sense amplifier circuit and configured to generate the first precharge enable signal and the second precharge enable signal based on a precharge enable signal, wherein when a test write operation and a test read operation are performed on the memory cell, the first precharge enable signal switches a voltage level thereof to make a logic level of the second precharge enable signal different from a logic level of the first precharge enable signal, and after the test write operation and the test read operation are completed, the second precharge enable signal switches the voltage level thereof for restoring the logic level of the second precharge enable signal to be the same as the logic level of the first precharge enable signal.
