| Zusammenfassung: | A dual access DRAM includes first and second sets of data lines. By adding a second set of multiplexing transistors to data lines that are controlled with timing and addressing similar to an existing set of multiplexing transistors, data can be transferred to a second subarray by way of an additional set of data lines. The second set of data lines are additional internal read/write lines used in addition to the normal set of data lines. The second set of data lines are designed to have short lengths with correspondingly low capacitance so that additional loading on the sense amplifiers is small. |
