Abstract
An improved method and device for column decoding for flash memory devices utilizes a burst page with a length greater than the length of a logical page. When a misalignment of an initial address occurs, valid reads across logical page boundaries are possible. The memory device enters the wait state only when a read crosses a burst page boundary. This minimizes the amount of time in which the memory device enters the wait state. In the preferred embodiment, this is achieved with a different management of the control signals that feed the third level of a three-level decoding stage column decoder. Changes to the architecture or in the number of column decoder selectors are not required. The memory access time during synchronous reads is thus improved.
