Abstract:
Systems and method are provided for a memory circuit. In embodiments, the circuit includes a plurality of memory cells corresponding to a word of data and a global write word line. A plurality of local write lines are connected to a subset of the plurality of memory cells of the word of data. Selection logic is configured to activate a particular subset of memory cells for writing via a particular local write line based on a signal on the global write line and a selection signal associated with the particular subset of memory cells.
