512K x 8 Bit NAND Flash Memory
The KM29W040A 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 typically 500
μ
s and an Erase operation erase
a 4K-byte block in typically 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 com-
mand inputs. The on-chip write controller automates the pro-
gram and erase operations, including program or erase pulse
repetition where required, and performs internal verification of
cell data.
The KM29W040A 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.
