512k X 8 Bit Nand Flash Memory SemiconductorThe K9F4008W0A is a 512Kx8bit NAND Flash Memory. Its
NAND cell structure provides the most cost-effective solution
for Digital Audio Recording. A Program operation programs a
32-byte frame in typical 500ms and an Erase operation erase a
4K-byte block in typical 6ms. Data in a frame CAN be read out at
a burst cycle rate of 120ns/byte. The I/O pins serve as the ports
for address and data input/output as well as for command
inputs. The on-chip write controller automates the program and
erase operations, including program or erase pulse repetition
where required, and performs internal verification of cell data.
The K9F4008W0A is an optimum solution for Flash memory
application that do not require the high performance levels or
capacity of larger density Flash Memories These application
include data storage in digital Telephone Answering
Devices(TAD) and other consumer applications that require
voice data storage. By Samsung Semiconductor, Inc.
