Abstract

According to one embodiment, when a command executed in a nonvolatile memory is an erase/program command and when a cumulative weight value satisfies a condition that a first input is selected as an input of high priority, a memory system suspends execution of the erase/program command by transmitting a suspend command to the nonvolatile memory. The memory system repeats executing an operation of starting the execution of one read command of the first input and an operation of updating the cumulative weight by using the weight associated with the read command until read command no longer exists in the first input or until the condition that the cumulative weight is larger than the first value is not satisfied, and resumes the execution of the suspended erase/program command.

Abstract

According to one embodiment, a controller, in a case where a first difference between a first number of times of erase and a second number is equal to or smaller than a second threshold, executes a copy operation in a first mode, the second number of times of erase is larger than the first number of times of erase. In a case where the first difference is larger than the second difference, the controller executes the copy operation in a second mode. A ratio of a copy amount to a cumulative data write amount in a first mode is smaller than a ratio of the copy amount to the cumulative data write amount in the second mode. The cumulative data write amount is an amount of data written to the nonvolatile memory based on write commands.

Abstract

According to an embodiment, a controller acquires a first temperature detection value and executes an acquisition operation on a first storage area. The controller converts a first voltage value into a second voltage value representing the read voltage in a temperature set value based on the first temperature detection value and records the second voltage value. The acquisition operation is an operation of determining, by using the read voltages, whether memory cells are ON or OFF and acquiring the first voltage value representing the read voltage for suppressing error bits. After that, the controller acquires a second temperature detection value and converts the second voltage value into a third voltage value representing the read voltage in the second temperature detection value. The controller reads data from the memory cells by using, as the read voltage, a voltage indicated by the third voltage value.
