READ MEMORY Operations
READ MEMORY Operations
The device supports default reading and writing to an A[MAX:MIN] of A[23:0].
To execute READ MEMORY commands, S# is driven LOW. The command code is input
on DQn, followed by input on DQn of three address bytes. Each address bit is latched in
during the rising edge of the clock. The addressed byte can be at any location, and the
address automatically increments to the next address after each byte of data is shifted
out; therefore, the entire memory can be read with a single command. The operation is
terminated by driving S# HIGH at any time during data output.

Notes:
1. Yes in the "Supported" row for each protocol indicates that the command in that col-
umn is supported; when supported, a command's functionality is identical for the entire
column regardless of the protocol. For example, a FAST READ functions the same for all
three protocols even though its data is input/output differently depending on the pro-
tocol.
2. FAST READ is similar to READ, but requires dummy clock cycles following the address
bytes and can operate at a higher frequency (^fC).
