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.
