Memory system, storage apparatus, and control method

A storage apparatus, comprising:

• a non-volatile memory having a non-volatile storage region and capable of reading and writing data with respect to the storage region;
• a host interface circuit configured to receive, from a host device, external instruction information including an instruction that causes the non-volatile memory to read and write the data;
• a memory interface circuit configured to transmit internal instruction information corresponding to the external instruction information to the non-volatile memory;
• and
• a delay circuit configured to delay execution of the instruction by the non-volatile memory when a data amount read and written by the non-volatile memory is equal to or more than a first threshold value during unit time.

A control method in a memory system,

• the memory system comprising:
• a non-volatile memory having a non-volatile storage region and capable of reading and writing data from and to the storage region;
• and
• a controller configured to communicate with the non-volatile memory,
• the control method comprising:
• receiving, from a host device, external instruction information including an instruction that causes the non-volatile memory to read and write the data;
• generating internal instruction information for causing the non-volatile memory to execute the instruction based on the external instruction information;
• transmitting the internal instruction information to the non-volatile memory;
• and
• controlling a delay circuit based on a magnitude relationship between a data amount read and written by the non-volatile memory during unit time and a first threshold value, the delay circuit being configured to delay execution of the instruction.
