ABSTRACT:
A column select circuit and a sense amplifier for use in a ROM utilizing a dynamic or static row and column select scheme is provided. The column select circuit comprises a voltage divider utilizing MOS transistors which have the gate dimensions thereof sized in proportion to the gate dimensions of the transistors in the ROM. The column select circuit provides a biasing voltage which controls a column select transistor and which tracks variations in process and supply voltage thereby providing precise biasing of the column select transistor and decreasing the access time of the ROM. The sense amplifier comprises a source follower and an output buffer stage.
