    • A negative word line driver employs devices to maintain the potential difference between the active word line signal and the inactive word line signal while reducing the need for a significant negative voltage supply. One form of the negative word line driver employs an isolation element to couple the word line to ground when the inputs to the word line driver indicate the word line should not be active, while the word line is also coupled to the negative voltage supply. Another form of the form of the negative word line driver receives as inputs the voltages to be driven on the word line and can be implemented with fewer transistors but still allows the word line to be driven at a negative voltage with a reduced negative voltage supply.

    • A clock generating circuit for a pseudo dual port memory incorporates feedback, delays, and latches to ensure that the write (read) operation clock pulse is sufficiently spaced in time from the read (write) operation clock. The clock generating circuit receives an external clock, a read enable signal, a write enable signal, and a reset signal as inputs. Advantages include minimization of the clock cycle time and operation unaffected by the duty ratio of an external clock. Delay circuitry may be added such that the generated clock signal has sufficient fan out and is sufficiently stable.
