Patent ID: 6961275

Claim:
A device for breaking leakage current path of a memory cell of a memory device, comprising: a memory cell of a memory array, having a first bit line and a second bit line; a first breaking circuit, connected between the first bit line of the memory cell and a power supplying terminal and between the second bit line and the power supplying terminal, wherein when the memory cell fails and in standby state, the first bit line and the power supplying terminal are disconnected, and the second bit line and the power supplying terminal are disconnected, by the first breaking circuit connected; and a second breaking circuit, connected between the first bit line and a sense amplifier of the memory cell, and between the second bit line and the sense amplifier, wherein when the memory cell fails and in standby state, the first bit line and the sense amplifier are disconnected and the second bit line and the sense amplifier are disconnected by the second breaking circuit.
