Memory controller, memory system, and method of controlling memory controller

A memory system comprising:

• a memory cell having an address assigned to the memory cell;
• a time measuring unit configured to measure time elapsed from predetermined timing on the address where data is written;
• an elapsed time determination unit configured to determine whether the elapsed time exceeds a fixed amount of time upon receiving an instruction to read out the data from the address;
• and
• a read control unit configured to cause reading out the data from the address to pause in a case where the elapsed time is determined not to exceed the fixed amount of time.

A method of controlling a memory controller, the method comprising:

• a time measurement step of measuring, by a time measuring unit, time elapsed from predetermined timing on an address where data is written;
• an elapsed time determination step of determining, by an elapsed time determination unit, whether the elapsed time exceeds a fixed amount of time upon receiving an instruction to read out the data from the address;
• and
• a read control step of causing reading out of the data from the address to pause in a case where the elapsed time is determined not to exceed the fixed amount of time.
