Page Program

The Page Program operation is the standard oper-

ation to program data to the memory array.

The main area of the memory array is pro-

grammed by page, however partial page program-

ming is allowed where any number of bytes (1 to

528) or words (1 to 264) can be programmed.

The maximum number of consecutive partial page

program operations allowed in the same page is

three. After exceeding this a Block Erase com-

mand must be issued before any further program

operations can take place in that page.

Before starting a Page Program operation a Point-

er operation can be performed to point to the area

to be programmed. Refer to the Pointer Opera-

tions section and Figure 12. for details.

Each Page Program operation consists of five

steps (see Figure 17.):

1. one bus cycle is required to setup the Page

Program command

2. four bus cycles are then required to input the

program address (refer to Table 6.)

Figure 17. Page Program Operation

3. the data is then input (up to 528 Bytes/ 264

Words) and loaded into the Page Buffer

4. one bus cycle is required to issue the confirm

command to start the P/E/R Controller.

5. The P/E/R Controller then programs the data

into the array.

Once the program operation has started the Sta-

tus Register can be read using the Read Status

Register command. During program operations

the Status Register will only flag errors for bits set

to '1' that have not been successfully programmed

to '0'.

During the program operation, only the Read Sta-

tus Register and Reset commands will be accept-

ed, all other commands will be ignored.

Once the program operation has completed the P/

E/R Controller bit SR6 is set to ‘1’ and the Ready/

Busy signal goes High.

The device remains in Read Status Register mode

until another valid command is written to the Com-

mand Interface.
