Abstract:
1. A semiconductor memory storage device for storing data comprising: a plurality of storage cells for storing said data, each storage cell comprising an access control device configured to provide said storage cell with access to or isolation from a data access port in response to an access control signal; access control circuitry configured to transmit said access control signal along one of a plurality of access control lines to control a plurality of said access control devices connected to said one of said plurality of access control lines; said access control circuitry comprising: said access control circuitry is configured to respond to a data access request signal to access a selected storage cell connected to a corresponding selected access control line to: control said voltage control switching circuitry to connect said at least one capacitor to said voltage supply line such that said at least one capacitor is charged by said voltage supply line and a voltage level on said voltage supply line is reduced; and to control said access control line switching circuitry to connect said selected access control line to said voltage supply line having said reduced voltage level.
