10-14. Read Identification (RDID)

The RDID instruction is for reading the manufacturer ID of 1-byte and followed by Device ID of 2-byte. The Macronix

Manufacturer ID and Device ID are listed as "Table 6. ID Definition".

The sequence is shown as "Figure 26. Read Identification (RDID) Sequence (Command 9F)".

While Program/Erase operation is in progress, it will not decode the RDID instruction, so there's no effect on the cy-

cle of program/erase operation which is currently in progress. When CS# goes high, the device is at standby stage.

10-15. Read Electronic Manufacturer ID & Device ID (REMS)

The REMS instruction is an alternative to the Release from Power-down/Device ID instruction that provides both the

JEDEC assigned manufacturer ID and the specific device ID.

The REMS instruction is very similar to the Release from Power-down/Device ID instruction. The instruction is initi-

ated by driving the CS# pin low and shift the instruction code "90h" followed by two dummy bytes and one bytes ad-

dress (A7~A0). After which, the Manufacturer ID for Macronix and the Device ID are shifted out on the falling edge

of SCLK with most significant bit (MSB) first as shown in "Figure 27. Read Electronic Manufacturer & Device ID (REMS)

Sequence (Command 90)". The Device ID values are listed in "Table 6. ID Definition". If the one-byte address is

initially set to 01h, then the device ID will be read first and then followed by the Manufacturer ID. The Manufacturer

and Device IDs can be read continuously, alternating from one to the other. The instruction is completed by driving

CS# high.
