Read Data Bytes at Higher Speed (FAST_READ: 0Bh)
The FAST_READ command reads data from the memory array at the frequency (f
input, with a maximum speed of 104 MHz. The host system must first select the device by driving CS# low.
The FAST_READ command is then written to SI, followed by a 3-byte address (A23-A0) and a dummy byte.
Each bit is latched on the rising edge of SCK. The memory array data, at that address, are output serially on
SO at a frequency f
The FAST_READ command sequence is shown in
be at any location. The device automatically increments to the next higher address after each byte of data is
output. The entire memory array can therefore be read with a single FAST_READ command. When the
highest address is reached, the address counter reverts to 00000h, allowing the read sequence to continue
indefinitely.
The FAST_READ command is terminated by driving CS# high at any time during data output. The device
rejects any FAST_READ command issued while it is executing a program, erase, or Write Status Register
operation, and continues the operation uninterrupted. Note that the FAST_READ command is not valid in
parallel mode.
