  • Patent number: 6292013
    Abstract: A circuit and method comprising a multiplexer circuit, a select circuit and a buffer circuit. The multiplexer circuit may be configured to present a data bit in response to a first control signal. The select circuit may be configured to generate one or more first outputs in response to (i) the data bit and (ii) one or more first select signals. The buffer circuit may be configured to present one or more second outputs on a data bus in response to (i) the one or more first outputs and (ii) one or more second control signals. One of the second outputs may have a data state and the rest of the second outputs may have a high impedance state. The first and select signals may be generated by a logic circuit.

  • Patent number: 6055177
    Abstract: 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.
