  • Publication number: 20250077414
    Abstract: A solid-state storage device is provided. The solid-state storage device is electrically connected to a host. The solid-state storage device includes a controller, a cache memory, a volatile memory, and a non-volatile memory. The cache memory, the volatile memory, and the non-volatile memory are electrically connected to the controller. The cache memory includes a first region and a second region. The controller is configured to fetch an access command from the host, and to store the access command in the first region. The controller is further configured to back up the access command stored in the first region to the volatile memory. The controller is further configured to store the access command backed up in the volatile memory in the second region, and to execute the access command stored in the second region.

    Abstract: A solid-state storage device is provided. The solid-state storage device is electrically connected to a host. The solid-state storage device includes a controller, a non-volatile memory, and a volatile memory. The non-volatile memory is electrically connected to the controller. The volatile memory is electrically connected to the controller. The volatile memory includes a submission queue and a completion queue. The controller is configured to fetch an access command from the host, and record the access command in the submission queue. The access command corresponds to a first logical address. The controller is configured to determine whether a first write command is in the submission queue to generate a determination result. The first write command corresponds to a second logical address identical to the first logical address. The controller is configured to decide a processing method of the access command according to the determination result.

  • Patent number: 11320878
    Abstract: A working temperature calculation method for a storage device of a server is provided. Firstly, n detected temperatures are converted into n transformed temperatures according to a composite temperature algorithm. If all of the n transformed temperatures are lower than a strengthen heat dissipation trigger temperature, the lowest temperature of the n transformed temperatures is set as a working temperature of the storage device. If at least one of the n transformed temperatures is higher than the strengthen heat dissipation trigger temperature, the highest temperature of the n transformed temperatures is set as the working temperature. When the storage device receives a temperature read command from the host, the storage device sends an information about the working temperature to the host, and the host controls a heat dissipation mode of the heat dissipation mechanism according to the working temperature.
