Abstract:
A column access control apparatus comprises a column signal control unit for controlling a write CAS pulse signal and an internal CAS pulse signal in response to a first signal, and a column decoder for outputting a column decoding signal using an output signal of the column signal control unit and the first signal. The column signal control unit delays the internal CAS pulse signal and the write CAS pulse signal to output delayed signals when the first signal is activated.
