Patent ID: 8693237

Claim:
A single-ended static random access memory, comprising: at least one memory cell, comprising: a data-latching unit, having a first input-terminal, a second input-terminal, a first output-terminal and a second output-terminal, latching an input data received by the first input-terminal or the second input-terminal, and providing a storage data and the inverse data of the storage data at the first output-terminal and the second output-terminal respectively; a first switch, receiving a reference data and the first switch coupled to the second input-terminal, wherein the first switch makes the reference data transferred to the second input-terminal according to a first word-line signal; a second switch, receiving the reference data and the second switch coupled to the first input-terminal, wherein the second switch makes the reference data transferred to the first input-terminal according to a second word-line signal; and a data-transferring unit, coupled to a bit-line and the first output-terminal and the data-transferring unit deciding whether to transfer the reference data to the bit-line or not according to the storage data and a control signal; and a third switch, receiving the reference data and the control signal, the third switch coupled to the first switch, the second switch and the data-transferring unit, and transferring the reference data to the first switch, the second switch and the data-transferring unit according to the control signal.
