    摘要: An apparatus comprising a memory array having a first port and a one or more other ports and a control circuit configured to couple (i) a bitline of the first port to a corresponding bitline of the one or more other ports and (ii) a dataline of the first port to a corresponding dataline of the one or more other ports in response to the first port and the one or more other ports accessing a common address.

    摘要: A circuit and method for staggering a bitline precharge between particular sections of a memory array. The present invention may be implemented in memories having increasing depths to reduce unacceptably high precharge current requirements associated with high bitline loads. Since the particular memory sections of the memory array are turned on independently, the peak current necessary to charge the particular bitlines is limited. The present invention may be implemented in logic and may therefore be less sensitive to process and temperature variations.

    摘要: A circuit that may be used as a memory cell that may be capable of a differential write and a single ended read. The circuit generally comprises a memory storage element having a write bitline, a complement write bitline and a read bitline. One or more first gates may be configured to pass data on the write bitline and the inverted write bitline during a write operation. The write operation may occur in response to a write control signal. A second gate may be configured to pass data on from the storage element to the read bitline in response to read control signal. As a result, the circuit may be written by both the write bitline and the complement write bitline and may be read by the read bitline.
