NONVOLATILE MEMORY DATA RECOVERY AFTER POWER FAILURE
Abstract:
A method for data recovery after a power failure is disclosed. The method may include steps (A) to (D). Step (A) may determine that a last power-down of a solid-state drive was an unsafe power-down. Step (B) may search at least some of a plurality of pages of a nonvolatile memory of the solid-state drive to define an unsafe zone in response to the determining that the last power-down of the solid-state drive was the unsafe power-down. Step (C) may define a pad zone comprising one or more of the pages subsequent to the unsafe zone. Step (D) may resume operation of the solid-state drive by writing new data subsequent to the pad zone.
