摘要： A semiconductor memory includes memory cell blocks, a burst-length information generating circuit which generates burst-length information based on a burst length, and a block enable circuit which receives the burst-length information. The block enable circuit selectively enables one of the memory cell blocks when the burst length is equal to or shorter than a predetermined burst length and selectively enables a plurality of memory cell blocks based on the burst length when the burst length is longer than the predetermined burst length. Data are read from the above-mentioned one or plurality of memory cell blocks.

摘要： An input circuit has an input buffer and a detection circuit. The input buffer receives an external signal and outputs an internal signal. The detection circuit detects whether or not the external signal is provided. The input buffer outputs the internal signal when an output of the detection circuit indicates that the external signal is provided. This arrangement shortens the lock-on time of an internal circuit (synchronous circuit).
