A25L016 Series  
Read Electronic Manufacturer ID & Device ID (REMS)  
The Read Electronic Manufacturer ID & Device ID (REMS)  
instruction allows the 8-bit manufacturer identification code to  
be read, followed by one byte of device identification. The  
manufacturer identification is assigned by JEDEC, and has  
the value 37h for AMIC. The device identification is assigned  
by the device manufacturer, and has the value 14h for  
A25L016.  
If the one-byte address is set to 01h, then the device ID will  
be read first and then followed by the Manufacturer ID. On  
the other hand, if the one-byte address is set to 00h, then the  
Manufacturer ID will be read first and then followed by the  
device ID.  
The instruction sequence is shown in Figure 18. The Read  
Electronic Manufacturer ID & Device ID (REMS) instruction is  
Any Read Electronic Manufacturer ID & Device ID (REMS)  
instruction while an Erase, or Program cycle is in progress, is  
not decoded, and has no effect on the cycle that is in  
progress.  
S
terminated by driving Chip Select ( ) High at any time during  
data output.  
S
When Chip Select ( ) is driven High, the device is put in the  
Stand-by Power mode. Once in the Stand-by Power mode,  
the device waits to be selected, so that it can receive, decode  
and execute instructions.  
S
The device is first selected by driving Chip Select ( ) Low.  
The 8-bit instruction code is followed by 2 dummy bytes and  
one byte address(A7~A0), each bit being latched-in on Serial  
Data Input (DIO) during the rising edge of Serial Clock (C).
