DEVICE OPERATION (CONTINUED)
READ COMMAND (READ DATA) OPERATION
The Read Data (READ) instruction is used to read memory
data of a IS25CD512/010 and IS25LD020 under normal
mode running up to 33 MHz.
The READ instruction code is transmitted via the SlO line,
followed by three address bytes (A23 - A0) of the first
memory location to be read. A total of 24 address bits are
shifted in, but only AMS (most significant address) - A0 are
decoded. The remaining bits (A23 – AMS) are ignored. The
first byte addressed can be at any memory location. Upon
completion, any data on the Sl will be ignored. Refer to Table
12 for the related Address Key.

The first byte data (D7 - D0) addressed is then shifted out on
the SO line, MSb first. A single byte of data, or up to the
whole memory array, can be read out in one READ
instruction. The address is automatically incremented after
each byte of data is shifted out. The read operation can be
terminated at any time by driving CE# high (VIH) after the
data comes out. When the highest address of the devices is
reached, the address counter will roll over to the 000000h
address, allowing the entire memory to be read in one
continuous READ instruction.
