In an example, the present invention provides a computing system. The system has a memory interface device comprising a counter, a dynamic random access memory device coupled to the memory interface device. The device comprises a plurality of banks, each of the banks having a subarray, each subarray having a plurality of memory cells. The device has a data interface coupled to the plurality of banks. The device has an address interface coupled to the plurality of banks, and a particular pre-charge command configured to be transferred to the memory interface device. The counter is adapted to count a measured time duration from a first time when data are available at the data interface to a second time when a pre-charge command is received by the address interface.
