NON-VOLATILE MEMORY DEVICE, AND STORAGE APPARATUS HAVING NON-VOLATILE MEMORY DEVICE

摘要

A non-volatile memory device includes a non-volatile memory and a memory controller which executes read from the non-volatile memory using a read option. The non-volatile memory includes a plurality of memory area units (e.g. dies described below), and each memory area unit includes a plurality of memory areas (e.g. pages). The memory controller holds management information in which a read option is recorded per memory area unit which is a unit larger than a memory area which is a read unit. The memory controller specifies a memory area unit including a read source memory area, selects a read option matching the specified memory area unit, and executes read from the read source memory area using the selected read option.
