  • Memory system, memory controller and operating method thereof
    Patent number: 11544002
    Abstract: A memory system, a memory controller and an operating method are disclosed. When a target command which instructs an operation of writing target data to a memory device is received from a host, the target data is divided into data units, and a first data unit among the data units is controlled such that the entire first data unit is written to the memory device or none of the first data unit is written to the memory device. As a consequence, it is possible to write data in specific units in a memory system using a multi-core.
    Type: Grant

  • Memory system, memory controller, and operation method
    Patent number: 11182108
    Abstract: Embodiments of the present disclosure relate to a memory system, a memory controller, and an operation method. The present disclosure may divide user data and map data corresponding to the user data into data segments, may input the data segments in N virtual die queues, and may program the same in a memory device, wherein a user data segment input in the virtual die queue is programmed according to two program schemes, thereby quickly programming the user data and the map data in the memory device and quickly updating the map data in a map cache.
