Abstract
A storage device includes a non-volatile memory including a buffer of a first size and a controller. The controller is configured to transmit a control command to the non-volatile memory, and then repeat a process including a first process of changing a phase value of a timing signal indicating timing to read or write data from or to the non-volatile memory and a second process of reading or writing data having a second size smaller than the first size from or to the non-volatile memory in synchronization with the timing signal of the changed phase value, a certain plurality of times without transmitting any other control command to the non-volatile memory during repetition of the process.

A storage device comprising:
- a non-volatile memory including a buffer of a first size;
- and
- a controller configured to transmit a control command to the non-volatile memory, and then to repeat a process including a phase changing process of changing a phase value of a timing signal indicating timing to read data from the non-volatile memory and a read process of reading data having a second size smaller than the first size from the buffer in the non-volatile memory to the controller in synchronization with the timing signal of the changed phase value, a certain plurality of times without transmitting any other control command to the non-volatile memory during repetition of the process.
A storage device comprising:
- a non-volatile memory including a buffer of a first size;
- and
- a controller configured to transmit a control command to the non-volatile memory, and then to repeat a process including a phase changing process of changing a phase value of a timing signal indicating timing to write data to the non-volatile memory and a write process of writing data having a second size smaller than the first size from the controller to the buffer in the non-volatile memory in synchronization with the timing signal of the changed phase value, a certain plurality of times without transmitting any other control command to the non-volatile memory during repetition of the process.
A method of controlling a non-volatile memory that includes a buffer of a first size, comprising:
- transmitting a control command to the non-volatile memory;
- and
- after transmitting the control command, repeating a process including a first process of changing a phase value of a timing signal indicating timing to read or write data from or to the non-volatile memory and a second process of reading or writing data having a second size smaller than the first size from or to the buffer in the non-volatile memory in synchronization with the timing signal of the changed phase value, a certain plurality of times without transmitting any other control command to the non-volatile memory during repetition of the process.
