GENERAL DESCRIPTION
The KH25L1605D are 16,777,216 bit serial Flash memory, which is configured as 2,097,152 x 8 internally. When it is in
two I/O read mode, the structure becomes 8,388,608 bits x 2. The KH25L3205D are 33,554,432 bit serial Flash memory,
which is configured as 4,194,304 x 8 internally. When it is in two I/O read mode, the structure becomes 16,772,216 bits
x 2. The KH25L6405D are 67,108,864 bit serial Flash memory, which is configured as 8,388,608 x 8 internally. When it
is in two I/O read mode, the structure becomes 33,554,432 bits x 2. (please refer to the "Two I/O Read mode" section).
The KH25L1605D/3205D/6405D feature a serial peripheral interface and software protocol allowing operation on a simple
3-wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). Serial
access to the device is enabled by CS# input.
When it is in two I/O read mode, the SI pin and SO pin become SIO0 pin and SIO1 pin for address/dummy bits input and
data output.
The KH25L1605D/3205D/6405D provides sequential read operation on whole chip.
After program/erase command is issued, auto program/ erase algorithms which program/ erase and verify the specified
page or sector/block locations will be executed. Program command is executed on byte basis, or page (256 bytes) basis,
or word basis for Continuously program mode, and erase command is executes on sector (4K-byte), or block (64K-byte),
or whole chip basis.
