Abstract
A memory system includes a non-volatile memory, a buffer memory, and a controller. The controller is configured to write data corresponding to a write command received from a host in the buffer memory, and based on an indication from the host, do not write the data stored in the buffer memory into the non-volatile memory unless a non-volatilization event occurs, the non-volatilization event being one of a flush request from the host and a detection of a power shutdown.

A memory system comprising:
- a non-volatile memory;
- a buffer memory;
- and
- a controller configured to:
- write data corresponding to a write command received from a host in the buffer memory;
- and
- based on an indication from the host, do not write the data stored in the buffer memory into the non-volatile memory unless a non-volatilization event occurs, the non-volatilization event being one of a flush request from the host and a detection of a power shutdown.
In a memory system including a buffer memory and a non-volatile memory, a method of suppressing writes to the non-volatile memory, said method comprising:
- writing data corresponding to a write command received from a host in the buffer memory;
- and
- based on an indication from the host, not writing the data stored in the buffer memory into the non-volatile memory unless a non-volatilization event occurs, the non-volatilization event being one of a flush request from the host and a detection of a power shutdown.
