摘要:
A static random access memory (SRAM) device comprises an array of memory cells, a plurality of bit line precharge circuit for selectively delivering current to bit lines in response to a pair of control signals, during normal and burn-in test modes, and a burn-in current source circuit for selectively delivering current to the memory cells selected by the word lines along with the precharge circuit, in response to the control signals, during the burn-in test mode. In burn-in write operation, memory cells can be supplied with enough cell current without large increasing of chip size and power consumption in normal operation mode.
