SEMICONDUCTOR DEVICE

摘要

A semiconductor device includes an equalizing circuit and a control circuit. The equalizing circuit executes an operation of pre-charging the signal input/output line pair used for data inputting/outputting and an operation of equalizing it independently of each other. In case a plurality of data write operations occur in succession, the control circuit halts pre-charge control in the equalizing circuit in the course of consecutive write operations.

主权项

1. A semiconductor device, comprising:
an I/O line pair composed by a first I/O line and a second I/O line; a precharge circuit provided between the first and second I/O lines to pre-charge the first and second I/O lines to a first potential in response to a first control signal; an equalizing circuit provided between the first and second I/O lines to short-circuit the first and second I/O lines in response to a second control signal; and a control circuit generating the first and second control signals independently of each other.
