Patent ID: 11899976
Assignee: SOLID STATE STORAGE TECHNOLOGY CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 4:
5. A write control method for a solid state storage device, the solid state storage device comprising a volatile memory and a non-volatile memory, the non-volatile memory being divided into a first area and a second area, the write control method comprising steps of:
(a) the solid state storage device being in a standby state when no command from a host is received;
(b) when a write command from the host is received, temporarily storing a write data from the host into the volatile memory; and
(c) storing the write data from the volatile memory into the non-volatile memory, and performing the step (a) again,
wherein the step (c) comprises sub-steps of:
(c1) monitoring a data amount of the write data continuously stored into the non-volatile memory;
(c2) before the data amount of the write data continuously stored into the non-volatile memory reaches a predetermined amount, storing the write data into plural buffering blocks of the first area in a first write mode; and
(c3) after the data amount of the write data continuously stored into the non-volatile memory reaches the predetermined amount, storing the write data into plural storing blocks of the second area in a second write mode,
wherein a write speed in the first write mode is faster than a write speed in the second write mode.
