Storage device and method of performing read and write operations

A method of controlling a read operation and a write operation at a storage device, the storage device having:

• core circuitry comprising one or more bitcells, each bitcell accessible via a corresponding bitline and wordline;
• column selection circuitry to, responsive to a column select signal, select at least one bitcell via one or more bitlines;
• wordline selection circuitry to, responsive to a wordline select signal, select the at least one bitcell via one or more wordlines;
• and
• control circuitry to operate in a first mode or second mode, the method comprising:
• providing, from the control circuitry operating in the first mode to the wordline selection circuitry, a first wordline select signal responsive to a first control signal;
• providing, from the control circuitry operating in the first mode to the column selection circuitry, first and second column select signals responsive to a second control signal, and wherein:
• the first column select signal is to control a read operation and the second column select signal is to control a write operation, and
• a transition of the second control signal triggers the read operation to complete and simultaneously triggers the write operation to begin.
