Variable sector size for a high density flash memory device

摘要

A variable sector size for a flash memory device is disclosed. The total available memory of the flash memory device is divided into sub-units. Each sub-unit has a pre-decoder coupled with it to enable operations on the memory within that sub-unit. A sector size control register is coupled with pre-decoder enabling logic which is coupled with the pre-decoders. The sector size control register and pre-decoder enabling logic determines how many pre-decoders, and therefore how many sub-units, are activated at a given time for a given memory operation.
