General Description
erasable (Flash), programmable memory containing
134,217,728 bits organized as 16,777,218 bytes (8 bits)
or 8,388,608 words (16 bits). This 128Mb device is
organized as one hundred twenty-eight 128KB erase
blocks.
as 8,388,608 bytes (8 bits) or 4,194,304 words (16 bits).
This 64Mb device is organized as sixty-four 128KB
erase blocks.
organized as 4,194,304 bytes (8 bits) or 2,097,152 words
(16 bits). This 32Mb device is organized as thirty-two
128KB erase blocks.
They also have common Flash interface (CFI) that per-
mits software algorithms to be used for entire families
of devices. The software is device-independent, JEDEC
ID-independent with forward and backward compati-
bility.
allows a single, simple software driver in all host sys-
tems to work with all SCS-compliant Flash memory
devices. The SCS provides the fastest system/device
data transfer rates and minimizes the device and sys-
tem-level implementation costs.
