A data processing system, which performs a neural network operation in response to a request from a host, comprising: a controller configured to receive control information and the input data from the host and to generate the output data by performing an operation on the input data and the weight, the control information including a scheme for storing a parameter including input data, output data, and a weight and a scheme for reusing the weight; and a memory device configured to store the weight according to control of the controller as the weight is transmitted from the host, wherein the controller includes an address converter configured to map a physical address provided from the host to a memory address based on the parameter storing scheme and the weight reusing scheme so that a bandwidth of a reading operation of the weight is maximized.

Data processing system performing neural network operations and operating method thereof

There are provided a memory controller and a memory system having the same. The memory controller includes: a temperature monitor device configured to count values that vary according to operation statuses of memory devices; a status check device configured to output status information of the memory devices based on the count values; and a scheduler configured to store the status information according to arrangements of the memory devices, and output the status information in response to a request received from a host.

Memory controller managing temperature of memory device and memory system having the memory controller

A memory controller includes a temperature monitor configured to update temperature states of a memory device divided into groups as temperature scores and a scheduler configured to update a command score using the temperature scores and change a priority of the command score to match with a current operation mode.
