15. NAND FLASH MEMORY – NAND512XXA2C (U162)
15.1.
General Description
The NAND flash 528-byte/ 264-word page is a family of non-volatile flash memories that uses the single
level cell (SLC) NAND technology. It is referred to as the small page family.
The NAND512R3A2C, NAND512R4A2C, and NAND512W3A2C have a density of 512 Mbits and operate with
either a 1.8 V or 3 V voltage supply. The size of a page is either 528 bytes (512 + 16 spare) or 264 words
(256 + 8 spare) depending on whether the device has a x8 or x16 bus width.
The address lines are multiplexed with the Data Input/output signals on a multiplexed x8 or x16
input/output bus. This interface reduces the pin count and makes it possible to migrate to other densities
without changing the footprint.
To extend the lifetime of NAND flash devices it is strongly recommended to implement an error
correction code (ECC). The use of ECC correction allows to achieve up to 100,000 program/erase cycles
for each block. A write protect pin is available to give a hardware protection against program and erase
operations.
