Abstract: A memory system includes a processor that includes cores and a memory controller, and a first semiconductor memory module that communicates with the memory controller. The cores receive a call to perform a first exception handling in response to detection of a first error when the memory controller reads first data from the first semiconductor memory module. A first monarchy core of the cores performs the first exception handling and the remaining cores of the cores return to remaining operations previously performed.

Abstract: A method is provided for refreshing a volatile memory. The method includes storing address information about a weak cell row address that is to be refreshed according to a weak cell refresh period that is shorter than a refresh period, performing a counting operation for generating a refresh row address, comparing the refresh row address with the address information, refreshing the weak cell row address when a result of the comparison shows that the refresh row address and the weak cell row address of the address information coincide with each other, changing the weak cell row address by changing a pointer of the address information, and refreshing the changed weak cell row address according to the weak cell refresh period.

Abstract: A memory system includes a nonvolatile memory module and a first controller configured to control the nonvolatile memory module. The nonvolatile memory module includes a volatile memory device, a nonvolatile memory device, and a second controller configured to control the volatile memory device and the nonvolatile memory device. The first controller may be configured to transmit a read request to the second controller. When, during a read operation according to the read request, normal data is not received from the nonvolatile memory device, the first controller may perform one or more retransmits of the read request to the second controller without a limitation on a number of times that the first controller performs the one or more retransmits of the read request.
