CIRCUIT FOR AND METHOD OF ENABLING THE TRANSFER OF DATA BY AN INTEGRATED CIRCUIT

摘要

A circuit for enabling the transfer of data by an integrated circuit is described. The circuit comprises a non-volatile memory array (610) coupled to receive a clock signal and having a plurality of memory elements storing data; and a control circuit (404) coupled to the non-volatile memory array, the control circuit enabling uni-directional transfer of data on a plurality of signal lines between the non-volatile memory array and the control circuit in a first mode and bi-directional transfer of data in a second mode; wherein the control circuit controls the transfer of data on the plurality of signal lines between the non- volatile memory array and the control circuit in the first mode on both the rising and falling edges of the clock signal. A method of enabling the transfer of data by an integrated circuit device is also described.
