Non-volatile memory device having configurable page size

Abstract

A flash memory device having at least one bank, where the each bank has an independently configurable page size. Each bank includes at least two memory planes having corresponding page buffers, where any number and combination of the memory planes are selectively accessed at the same time in response to configuration data and address data. The configuration data can be loaded into the memory device upon power up for a static page configuration of the bank, or the configuration data can be received with each command to allow for dynamic page configuration of the bank. By selectively adjusting a page size the memory bank, the block size is correspondingly adjusted.

Background technique

[0003] Flash memory is a common type of non-volatile memory that is widely used as a storage device in consumer electronics and mass storage applications. Flash memory is commonly used in mass consumer products, such as digital audio / video players, cellular phones, and digital video cameras, to store application data and / or media data. Flash memory can also be used as a dedicated storage device, such as a portable flash drive that can be plugged into a universal serial port (USB) of a personal computer, and, for example, as a replacement for a magnetic hard disk drive (HDD). Flash memory is known to be non-volatile, meaning it ...
