Abstract
A semiconductor memory storage device for storing data including: a plurality of storage cells, each storage cell including an access control device configured to provide the storage cell with access to or isolation from a data access port in response to an access control signal. Access control circuitry includes: access switching circuitry configured to connect a selected access control line to a voltage source; and feedback circuitry configured to feedback a change in voltage on the access control line to the access switching 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 in response to the feedback circuitry providing a feedback signal indicating that the access control line voltage has attained a predetermined value.
