Erase Page Operation

The Erase Page operation is initiated when the ERASEPAGE pin is asserted. The Erase Page operation

allows the user to erase (set user data to zero) any page within the FB.

The use of the OVERWRITEPAGE and PAGELOSSPROTECT pins is the same for erase as for a

Program Page operation.

As with the Program Page operation, a STATUS of '01' indicates that the addressed page is not erased.

A waveform for an Erase Page operation is shown in Figure 2-37.

Erase errors include the following:

1. Attempting to erase a page that is Overwrite Protected (STATUS = '01')

2. Attempting to erase a page that is not in the Page Buffer when the Page Buffer has entered Page

Loss Protection mode (STATUS = '01')

3. The Write Count of the erased page exceeding the Write Threshold defined in the part

specification (STATUS = '11')

4. The ECC Logic determining that there is an uncorrectable error within the erased page (STATUS

= '10')
