摘要： A method of testing internal signals of a memory for timing marginalities which may result in unstable operation includes: delaying internal address signals of the memory by an amount great enough so that data cannot be validly written to and read from memory locations which are accessed by address signals having timing marginalities which are delayed but small enough so that data can be validly written to and read from memory locations which are accessed by address signals not having such timing marginalities which are delayed. Data is then written to and read from memory locations which are accessed by delayed address signals, and a determination is made as to whether the data read from any memory location does not correspond with the data written to such memory location.

摘要： Embodiments of the invention provide a method, apparatus, and system for operating a memory device. In one embodiment, an inverted refresh command is received. In response to receiving the inverted refresh command, an all bank precharge command is issued. After the all bank precharge command is issued, an all bank activate command is issued, causing wordlines identified by a row address counter to be activated. The identified wordlines are maintained in activated state until a subsequent inverted refresh command is received.

摘要： A method for manufacturing a multiple-chip memory device includes making a volatile memory element on a semiconductor substrate, examining the volatile memory element for one or more initial errors, correcting the one or more initial errors on the semiconductor substrate, incorporating the volatile memory element into the multiple-chip memory device, and incorporating a non-volatile memory element into the multiple-chip memory device. The volatile memory element is examined for one or more secondary errors, after incorporating the volatile memory element and the non-volatile memory element into the multiple-chip memory device. Repair information is stored in a non-volatile memory element, the repair information identifying the one or more secondary errors.
