WRITE OPERATIONS

Commands are written to the COMMAND INTERFACE

REGISTER (CIR) using standard microprocessor write

timings. The CIR serves as the interface between the

microprocessor and the internal chip operation. The

CIR can decipher Read Array, Read Silicon ID, Erase

and Program command. In the event of a read command,

the CIR simply points the read path at either the array

or the silicon ID, depending on the specific read command

given. For a program or erase cycle, the CIR informs

the write state machine that a program or erase has

been requested. During a program cycle, the write state

machine will control the program sequences and the

CIR will only respond to status reads. During a sector/

chip erase cycle, the CIR will respond to status reads

and erase suspend. After the write state machine has

completed its task, it will allow the CIR to respond to its

full command set. The CIR stays at read status register

mode until the microprocessor issues another valid

command sequence.

Device operations are selected by writing commands

into the CIR. Table 3 below defines 16 Mbit flash family

command.
