A memory controller is provided that is configured to control a memory accessed by a device connected to a host processor via a bus. The memory controller is configured to control a memory accessed by a device connected to a host processor via a bus, and includes a first interface circuit configured to communicate with the host processor; a second interface circuit configured to communicate with the memory; an error detection circuit configured to detect an error present in data received from the second interface circuit in response to a first read request received from the first interface circuit; a variable error correction circuit configured to correct the error based on at least one of a reference latency and a reference error correction level included in a first error correction option; and a fixed error correction circuit configured to correct the error in parallel with an operation of the variable error correction circuit.

Memory controller performing selective and parallel error correction, system including the same and operating method of memory device

A device configured to communicate through a bus may include a first interface circuit configured to, based on a first protocol, provide first access to a first memory through the bus and a second interface circuit configured to, based on a second protocol, provide a non-coherent input/output (I/O) interface through the bus. The second interface circuit may be configured to access the first memory in response to a message received through the bus based on the second protocol to provide second access to the first memory through the bus.

System, device, and method for accessing memory based on multi-protocol

A memory system includes a memory device including a memory cell array, a first latch, a plurality of program latches, and a second latch and a memory controller configured to provide a command to the memory device. The memory device may sense first data from a first region of the memory cell array, store the sensed first data in the first latch, transfer the sensed first data to the second latch, output the first data from the second latch to the memory controller, and transfer the first data from the second latch to a first program latch of the plurality of program latches, in response to a first read command.

Memory device, memory system including the same, and operating method of the memory system

A device connected to a host processor via a bus includes: an accelerator circuit configured to operate based on a message received from the host processor; and a controller configured to control an access to a memory connected to the device, wherein the controller is further configured to, in response to a read request received from the accelerator circuit, provide a first message requesting resolution of coherence to the host processor and prefetch first data from the memory.
