KM29W32000ATS Overview

GENERAL DESCRIPTION
The KM29W32000A is a 4M(4,194,304)x8bit NAND Flash Memory with a spare 128K(131,072)x8bit. Its NAND cell provides the most cost-effective solution for the solid state mass storage market. A program operation programs the 528-byte page in typically 250ms and an erase operation can be performed in typically 2ms on an 8K-byte block.
Data in the page can be read out at 50ns cycle time per byte. The I/O pins serve as the ports for address and data input/output as well as command inputs. The on-chip write controller automates all program and erase system functions, including pulse repetition, where required, and internal verify and margining of data. Even the write-intensive systems can take advantage of the KM29W32000A extended reliability of one million program/erase cycles by providing either ECC(Error Correction Code) or real time mapping-out algorithm. These algorithms have been implemented in many mass storage applications and also the spare 16 bytes of a page combined with the other 512 bytes can be utilized by system-level ECC.
The KM29W32000A is an optimum solution for large nonvolatile storage application such as solid state storage, digital voice recorder, digital still camera and other portable applications requiring nonvolatility.
