A method and system for limiting resource usage of a version store. In one embodiment, an input signal is fed into the source of a common-gate pMOSFET, the output signal is taken at the drain of the common-gate pMOSFET, and bias current is supplied by a pMOSFET and a nMOSFET biased in their triode regions. At least one skirt retainer is supported on at least one of the side walls. The host server periodically queries the tape storage device to learn the current tape position, and concludes the transaction when the tape storage device has written past the calculated position. The memory module includes a memory module controller coupled to the system memory controller and a plurality of memory devices coupled to the memory module controller.
