The KM29U64000 is a 8M(8,388,608)x8bit NAND Flash Mem-
ory with a spare 256K(262,144)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 200 s and an erase operation can be performed in typ-
ically 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
functions including pulse repetition, where required, and inter-
nal verify and margining of data. Even the write-intensive sys-
tems can take advantage of the KM29U64000 s extended
reliability of 1,000,000 program/erase cycles by providing either
ECC(Error Correcting Code) or real time mapping-out algo-
rithm. 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 KM29U64000 is an optimum solution for large nonvolatile
storage applications such as solid state file storage, digital
voice recorder, digital still camera and other portable applica-
tions requiring non-volatility.
