Read Identification (RDID)
The Read Identification (RDID) command outputs the one-byte manufacturer identification, followed by the
two-byte device identification, to the host system.
JEDEC assigns the manufacturer identification byte; for Spansion devices it is 01h. The device manufacturer
assigns the device identification: the first byte provides the memory type; the second byte indicates the
memory capacity. See
The host system must first select the device by driving CS# low. The RDID command is then written to SI,
and each bit is latched on the rising edge of SCK. The 24-bit device identification data is output from the
memory array on SO at a frequency f
The RDID command sequence is shown in
Driving CS# high after the device identification data has been read at least once terminates the READ_ID
command. Driving CS# high at any time during data output also terminates the RDID operation.
The device rejects any RDID command issued while it is executing a program, erase, or Write Status Register
operation, and continues the operation uninterrupted.
