SDRAM, the read data can be latched in a port circuit so that the CPU can read the data in the
next state. When this read data shift function is used, the read cycle requires additional one
state. The write cycle is not affected. The timing waveforms for various cases are shown below.
If the AC specifications of the SDRAM cannot be satisfied when data is read from the
(a) 1-word read, the read data shift function disabled (SDACR<SRCS> = “0”)
(b) 1-word read, the read data shift function enabled (SDACR<SRDS> = “1”,
NOP
<SRDSCK>= “0”)
