摘要： A command control circuit includes a read-clock generation circuit that generates a read clock ICLK-R at the time of reading, a write-clock generation circuit that generates a write clock ICLK-W at the time of writing, and a burst chop AL counter that counts an additive latency of a burst chop command. The burst chop AL counter counts the burst chop command in synchronization with both the read clock ICLK-R and the write clock ICLK-W. This eliminates a need of separately arranging an AL counter that counts the burst chop command at the time of reading and an AL counter that counts the burst chop command at the time of writing.

摘要： In a semiconductor integrated circuit device, a write command decoder decodes a write command and outputs decode pulses. A command counter circuit counts the decode pulses as the number of commands. A latch circuit latches the write aDDRess in response to a count output from the command counter circuit. A latency counter circuit counts a latency in response to the decode pulses. The semiconductor integrated circuit device further includes a circuit for turning on a column selection control signal when the count value of the latency counter circuit exceeds a predetermined latency value and a circuit for outputting the aDDRess latched by the latch circuit as a column aDDRess in response to the column selection control signal being turned on. The semiconductor integrated circuit device performs a write operation to the column aDDRess in response to the column selection control signal being turned on.
