  • Patent number: 11416393
    Abstract: A method for performing a copyback procedure is described. The method includes determining to move first encoded data from a first location in a memory die to a second location. In response to determining to move the first encoded data from the first location to the second location, a starting seed, which is associated with the first location, is combined with a destination seed, which is associated with the second location, to produce a combined seed. Based on the combined seed, the method determines a pseudorandom sequence based on the combined seed and a pseudorandom sequence table, wherein the pseudorandom sequence table maps seed values to pseudorandom sequences and the determined pseudorandom sequence maps to the combined seed in the pseudorandom sequence table. The method further combines the first encoded data with the pseudorandom sequence to produce second encoded data for storage in the second location.

  • Patent number: 11397679
    Abstract: Methods, systems, and devices that support variable modulation schemes for memory are described. A device may switch between different modulation schemes for communication based on one or more operating parameters associated with the device or a component of the device. The modulation schemes may involve amplitude modulation in which different levels of a signal represent different data values. For instance, the device may use a first modulation scheme that represents data using two levels and a second modulation scheme that represents data using four levels. In one example, the device may switch from the first modulation scheme to the second modulation scheme when bandwidth demand is high, and the device may switch from the second modulation scheme to the first modulation scheme when power conservation is in demand. The device may also, based on the operating parameter, change the frequency of the signal pulses communicated using the modulation schemes.

  • Patent number: 11341045
    Abstract: A memory apparatus and a method for processing data the same are suggested to process 10-bit or 12-bit data. A processor that uses 10-bit or 12-bit data can efficiently store 10-bit or 12-bit data and provide a flexible memory access method that reduces memory usage. To this end, by adding a new memory bank that is ¼ of the size of an existing memory bank word, when storing data in 10-bit units, 2 out of 10 bits can be stored in a new memory bank to reduce memory waste. In addition, when 8-bit data is stored using a flexible memory structure, data can be stored in the same way as a previously operated memory bank.

  • Patent number: 11334258
    Abstract: A new approach is proposed to support hardware-based memory region protection for an electronic device. One or more sources/requesting access to a memory/storage that is local to or associated with the electronic device are categorized into at least two types—a set of trusted sources and a set of untrusted sources. Accordingly, a memory manager is configured to partition the memory into a plurality of regions including at least a secure region that is accessible only by a trusted source and a non-secure region that is accessible by an untrusted source. Any access attempt to the secure region by one of the untrusted sources will be blocked. During operation, the memory manager is configured to dynamically adjust the demarcation and/or size of the secure region and the non-secure region of the memory via remapping of the memory based on current access need to data maintained in the memory.

  • Patent number: 11327666
    Abstract: A subset of drives with protection groups that have D data members and P parity members is scaled in single drive increments. A plurality of indexed partitions equal in size and number are created on (D+P) indexed drives. Protection groups that have D data members and P parity members are created on individual partition indexes of the (D+P) drives. When a new drive is added some of the protection group members located on the (D+P) drives are selected using modulo arithmetic. The selected protection group members are relocated to the new drive and new protection groups are created using the partitions made available due to the relocations. When (D+P) new drives have been added the drive subset may be split into two drive subsets. The modulo arithmetic may include selecting the members of protection group X that are on partition X of drive Y that satisfy the condition (X?Y+N?1) modulo W=0, where N is a count of new drives added to the (D+P) drives and W=(D+P).

  • Patent number: 11327654
    Abstract: A method for a baseboard management controller mounting a folder with KVM includes following steps. A first size of a to-be-mounted folder is calculated. A second size of a mirror image file corresponding to the to-be-mounted folder is calculated based on the first size. A default storage path is allocated for the mirror image file, and it is obtained a remaining storage capacity of a disk where the default storage path is located. If the remaining storage capacity is less than the second size, a prompt dialog box, for selecting a user storage path for the mirror image file, is displayed to the user. If the remaining storage capacity of the disk where the default storage path or the user storage path is located is greater than the second size, the to-be-mounted folder is mounted to a server.

  • Patent number: 11314427
    Abstract: Methods, systems, and devices for memory device with enhanced data reliability capabilities are described. For a write operation, a memory device may receive a write command from a host device indicating a first set of data. The memory device may determine to operate in first mode of operation associated with a reliability above a threshold and generate a second set of data to store with the first set of data based on operating in the first mode of operation. For a read operation, the memory device may identify that a read command received from a host device is associated with the first mode of operation. Based on operating in the first mode of operation, the memory device may select one or more reference thresholds (e.g., a subset of reference thresholds) to retrieve the first set of data and transmit the first set of data to the host device.
