Quad Page Program (33h)

The ‘ Quad Page Program’ instruction is to program the memory as being “0” at previously erased memory areas. The ‘Quad

Page Program’ requires four pins: I/O0, I/O1, I/O2 and I/O3, as address and data inputs, which can improve performance. A

system using a faster clock speed does not get more benefit for the Quad Page Program as the required internal page program

time is far more than the time data clock-in.

To use ‘Quad Page Program’ instruction, the Quad Enable bit must be set. A Write Enable instruction must be executed

before the device accepts the ‘Quad Page Program’ instruction (Status Register-1, WEL = 1). The instruction is initiated

by driving the CS pin low then sending the instruction code “33h” with following a 24-bit address (A23-A0) and at least

one data, into the I/O pins. The CS pin must be held low for the entire length of the instruction while data is being sent to

the device. All other functions of ‘ Quad Page Program’ instruction are the same as the standard ‘ Page Program’

instruction. (Please refer to Figure 7-24 and Figure 7-25).
