Uniform SECTOR Dual and Quad Serial Flash

VER 1.5

Quad Output Fast Read (6BH)

The Quad Output Fast Read command is followed by 3-byte address (A23-A0) and a dummy byte,

each bit being latched in during the rising edge of SCLK, then the memory contents are shifted out

4-bit per clock cycle from IO3, IO2, IO1 and IO0. The command sequence is shown in followed

Figure9. The first byte addressed can be at any location. The address is automatically incremented to

the next higher address after each byte of data is shifted out.

Figure9. Quad Output Fast Read Sequence Diagram

Dual I/O Fast Read (BBH)

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

capability to input the 3-byte address (A23-0) and a “Continuous Read Mode” byte 2-bit per clock by

SI and SO, each bit being latched in during the rising edge of SCLK, then the memory contents are

shifted out 2-bit per clock cycle from SI and SO. The command sequence is shown in followed

Figure10. The first byte addressed can be at any location. The address is automatically incremented

to the next higher address after each byte of data is shifted out.
