  • Controlling a voltage level of an access signal to reduce access disturbs in semiconductor memories
    Patent number: 8611172
    Abstract: A semiconductor memory storage device having a plurality of storage cells for storing data, each storage cell comprising an access control device and access control circuitry. The 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 the voltage control switching circuitry to connect the at least one capacitor to the voltage supply line such that the at least one capacitor is charged by the voltage supply line and a voltage level on the voltage supply line is reduced; and to control the access control line switching circuitry to connect the selected access control line to the voltage supply line having the reduced voltage level.
    Type: Grant
