Abstract
A read retry method for a solid state storage device is provided. The solid state storage device is in communication with a host. The solid state storage device includes a non-volatile memory. The read retry method includes the following steps. Firstly, the solid state storage device judges whether a specified read block of the non-volatile memory is in a specified failure mode. If the specified read block of the non-volatile memory is in the specified failure mode, a failure mode read retry process corresponding to the specified failure mode is performed. If an accurate read data is acquired in the failure mode read retry process, the accurate read data is transmitted to the host. If the accurate read data is not acquired in the failure mode read retry process, a read fail message is sent to the host.
