| 摘要 |
A semiconductor integrated circuit includes a first pad allocated to receive a row address, a second pad allocated to discriminate a first input/output mode and a second input/output mode, a detector configured to generate a detection signal in response to logic levels of the first and second pads, and a column address controller configured to deassert a column address to a logic low level in response to a deasserted detection signal. The semiconductor integrated circuit may selectively support one of first and second memory capacities and one of the first and second input/output modes using the logic levels of the first and second pads. |
