Serial NOR Flash Memory

128 Megabits 3.0V Quad I/O Serial Flash Memory with 4KB Uniform Sector

VER 1.1

Quad I/O Fast Read(EBH)

The Quad I/O Fast Read command is similar to the Dual I/O Fast Read command but with the capability

to input the 3-byte address (A23-0) and a “Continuous Read Mode” byte and 4-dummy clock 4-bits per

clock by IO0, IO1, IO3, IO4, each bit being latched in during the rising edge of SCLK, then the memory

contents are shifted out 4-bit per clock cycle from IO0, IO1, IO2, IO3. The command sequence is shown in

Figure 12. The first byte addressed can be at any location. The address is automatically incremented to

the next address after each byte of data is shifted out. The Quad Enable bit (QE) of Status Register (S9)

must be set to enable for the Quad I/O Fast read command.
