Memory system

A memory system comprising:

• a first nonvolatile memory;
• a second memory;
• a first processor;
• and
• a second processor,
• wherein the first processor is configured to:
• calculate a first assignment amount indicating an operation time of the first nonvolatile memory,
• write the first assignment amount to the second memory, and
• cause the second processor to be transitioned to a second mode in response to receiving an exhaustion notification from the second processor, and
• wherein the second processor is configured to:
• perform access to the first nonvolatile memory in a first mode,
• calculate a consumed amount indicating an operation time of the first nonvolatile memory in the access,
• transmit the exhaustion notification to the first processor when the consumed amount reaches the first assignment amount in the second memory, and
• stop access to the first nonvolatile memory in the second mode,
• wherein the first processor is configured to set each of a plurality of second assignment amounts, and
• wherein the second processor is configured to:
• determine that the plurality of second assignment amounts include a first one of second assignment amount and a second one of second assignment amount, the first one of second assignment amount is different from the second one of second assignment amount, and
• transmit the exhaustion notification to the first processor when the consumed amount reaches a total amount of the first one of second assignment amount and the second one of the second assignment amount among the second assignment amounts.
