ABSTRACT:
A bit line decoding circuit for accessing an array of two-bit memory cells. Two adjacent memory cells can be accessed by applying appropriate voltages to the terminals of the cells. A bit line decoder selects plural bit lines in the memory array and provides paths to apply or receive the voltages to or from the selected bit lines. In one embodiment, shared control gates of pass transistors which function as the bit line selection in a bit line deocder provides reduction in the number of control signals. Functions of applying a voltage for neighbor effect reduction and of providing a path for a reference voltage are also implemented in further embodiments.
