  • Patent number: 11900984
    Abstract: A block of dynamic memory in a DRAM device is organized to share a common set of bitlines may be erased/destroyed/randomized by concurrently activating multiple (or all) of the wordlines of the block. The data held in the sense amplifiers and cells of an active wordline may be erased by precharging the sense amplifiers and then writing precharge voltages into the cells of the open row. Rows are selectively configured to either be refreshed or not refreshed. The rows that are not refreshed will, after a time, lose their contents thereby reducing the time interval for attack. An external signal can cause the isolation of a memory device or module and initiation of automatic erasure of the memory contents of the device or module using one of the methods disclosed herein. The trigger for the external signal may be one or more of temperature changes/conditions, loss of power, and/or external commands from a controller.
