Abstract
A memory system and a data processing system including the memory system may manage a plurality of memory devices. For example, the data processing system may categorize and analyze error information from the memory devices, acquire characteristic data from the memory devices and set operation modes of the memory devices based on the characteristic data, allocate the memory devices to a host workload, detect a defective memory device among the memory devices and efficiently recover the defective memory device.
Claims8
A data processing system comprising:
- a memory system including a plurality of memory devices each having type depending on latency for read and write operation;
- and
- a compute system coupled to the memory system,
- wherein the compute system includes a database memory suitable for storing a write-to-read-ratio information indicating a ratio of write operation to read operation of respective types of workloads, and allocates a memory device, for processing a current workload, based on the type of the memory device and the write-to-read-ratio information of the current workload.
1 more element
A memory system comprising:
- a plurality of memory devices including a spare memory device;
- and
- a controller suitable for controlling the plurality of memory devices, and
- wherein the controller periodically checks whether each of the plurality of memory devices is a defective memory device, copies data from the defective memory device to the spare memory device and cuts off a power of the defective memory device.
1 more element
A data processing system comprising:
- a plurality of memory systems;
- and
- a compute system configured to deliver requests among the plurality of memory systems based on a global map that includes information on each of the plurality of memory systems,
- wherein each of the plurality of memory systems includes:
- a plurality of normal memory devices and a shared memory device;
- and
- a controller suitable for controlling the plurality of normal memory devices and the shared memory device, and
- wherein the controller provides a power to the plurality of normal memory devices and the shared memory device independently, receives a request provided from other memory system, provides requested data to the other memory system from target memory device among the plurality of memory devices based on meta information of data for the request and copy the requested data into the shared memory device.
