The OTP cell logic uses the plurality of OTP cells to select the portion of the block as corresponding to the OTP cell. This portion of the block is write protected when the OTP cell is placed in the second state.

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.
