Abstract
The present invention provides a technique for performing write operations within a memory device comprising an array of memory cells. Wordline driver circuitry is used to assert a wordline signal to activate an addressed memory cell in the array. Write driver circuitry is used to perform a write operation to write a data value into the addressed memory cell, and is responsive to assertion of a write assist enable signal during the write operation to implement a write assist mechanism. Further, control circuitry is used to control timing of assertion of the wordline signal in dependence on timing of assertion of the write assist enable signal. By making the timing of assertion of the wordline signal dependent on the timing at which the write assist enable signal is asserted, it has been found that writeability of the memory cells is significantly improved.
