Abstract
To perform both writing and reading at a high speed by utilizing a first memory and a second memory that has a lower writing speed and a higher reading speed than the first memory. A writing unit writes writing data related to a writing command in a first memory when the writing command is executed. A transfer unit transfers the writing data from the first memory to a second memory at a predetermined timing. A reading unit performs reading of reading data from the second memory with higher priority than from the first memory when a reading command is executed.
Claims15
A memory control device comprising:
- a writing unit that writes writing data related to a writing command in a first memory when the writing command is executed;
- a transfer unit that transfers the writing data from the first memory to a second memory at a predetermined timing;
- and
- a reading unit that performs reading of reading data from the second memory with higher priority than from the first memory when a reading command is executed.
A storage device comprising:
- a first memory;
- a second memory that has a lower writing speed and a higher reading speed than the first memory;
- a writing unit that writes writing data related to a writing command in the first memory when the writing command is executed;
- a transfer unit that transfers the writing data from the first memory to the second memory at a predetermined timing;
- and
- a reading unit that performs reading of reading data from the second memory with higher priority than from the first memory when a reading command is executed.
An information processing system comprising:
- a first memory;
- a second memory that has a lower writing speed and a higher reading speed than the first memory;
- a host computer that issues a command related to the first memory or the second memory;
- a writing unit that writes writing data related to a writing command in the first memory when the writing command is executed;
- a transfer unit that transfers the writing data from the first memory to the second memory at a predetermined timing;
- and
- a reading unit that performs reading of reading data from the second memory with higher priority than from the first memory when a reading command is executed.
