Read Device Identifier

The Read Device Identifier command instructs the device to output manufacturer code,

device identifier code, block-lock status, OTP register data, or configuration register

data (see Section 6.2, “Device Command Bus Cycles” on page 18 for details on issuing

the Read Device Identifier command). Table 8, “Device Identifier Information” on

page 22 and Table 9, “Device ID codes” on page 22 show the address offsets and data

values for this device.

7.4

Read CFI

The Read CFI command instructs the device to output Common Flash Interface data

when read.

Note:

The 512-Mbit devices do not have a Device ID associated with them. Each die within the stack can be identified by either

of the 256-Mbit Device ID codes depending on its parameter option.
