Abstract
A method and apparatus for dynamic programming and dynamic reading of a select non-volatile memory cell in a virtual grounds array is disclosed. In the dynamic read operation the global bit lines and the associated local bit lines are connected to a precharged voltage. One of the first or second global bit lines is connected to a low voltage such as ground, wherein the one global bit line connected to ground also connects to the local bit line for sensing the select non-volatile memory cell. The state of the select non-volatile memory cell is detected by detecting the sense amplifier connected to the global bit line, other than the one global bit line. In a dynamic programming operation, the first and second global bit lines and their associated local bit lines are precharged to a first voltage. One of the first or second global bit line and its associated local bit lines is connected to a second voltage.
