  • Patent number: 11742015
    Abstract: A memory system is provided to include a storage device including memory cells for storing data, and a controller in communication with an external device and configured to control the storage device based on a request from the external device. The controller is configured to receive a request from the external device to perform a refresh operation of re-writing stored data in the memory cells, read data from the memory cells included in the storage device, set a refresh period based on a number of fail bits included in the read data and a temperature of the controller or the storage device, and perform the refresh operation of the storage device based on the refresh period.

  • Patent number: 11587608
    Abstract: There are provided a volatile memory device, and an operating method. The volatile memory device includes: a plurality of memory cells arranged in rows and columns and structured to store data; word lines; bit lines; a row decoder; a column decoder; and a control logic coupled to communicate with the row and column decoders and configured to, in an active period, provide the row decoder with a first command, and provide the column decoder with a second command, wherein the row decoder is further configured to: apply a first word line voltage higher than a ground voltage to a selected word line, from when the first command is provided; and for a duration over which the row decoder is activated, apply either a second word line voltage lower than the first word line voltage to the selected word line or no voltage to the selected word line.

  • Publication number: 20230011582
    Abstract: A memory module includes a module substrate, a plurality of memory devices, a first power line, and a second power line. The memory devices are mounted on the module substrate. Each of the memory devices includes a power management member. The first power line may be arranged in the module substrate to provide each of the memory devices with power. The second power line may be electrically connected between the power management members of adjacent memory devices to control and share the power provided to the adjacent memory devices.
