(57) Abstract :
Embodiments of the invention provide a method performed by a serial flash controller and a serial flash memory that are
interconnected by a serial clock (SCK) line, a plurality of serial input/output (SIO) lines, and a latch line. The SCK line carries a
SCK clock from the serial flash controller to the serial flash memory. Under the method, the serial flash memory synchronously
transmits to the serial flash controller data bits through the SIO lines and a memory-generated latch signal through the latch line.
The serial flash controller uses the memory-generated latch signal instead of the SCK clock to latch the data bits received through
the SIO lines.
