ADDRESS COUNTER FOR NONVOLATILE MEMORY DEVICE

摘要

An address counter for a nonvolatile memory device includes a cascade of cells. Each cell includes an address counting flip-flop that is updated to a value of every newly counted address bit, or latches a column address bit value input by an external user of the memory device during ALE cycles for addressing a start memory location on a selected page. Each cell further includes an additional address loading flip-flop for loading the column address bit value input during ALE cycles for addressing the start memory location on the selected page during the ALE cycles. A logic circuit updates the address counting flip flop to the address bit value during a read confirm cycle in a read sequence, and during a first data input cycle in a program sequence.
