Abstract
A method is provided for accessing a storage cell of a dynamic random access memory (DRAM) having an array of gain cells being read accessible by a read wordline and a read bitline, and being write accessible by a write wordline and write bitline separate from said read wordline and read bitline. The method includes activating a read wordline of the array of gain cells to permit signals from a plurality of gain cells coupled to the read wordline to develop on a plurality of corresponding read bitlines coupled to the gain cells. An interlock signal is then generated in the DRAM after activating the read wordline. The read wordline is then deactivated in response to the interlock signal.
