摘要： A key-value storage architecture with data compression is shown. During the garbage collection, the controller compresses valid pieces of key-value data to generate a piece of compressed data. Each piece of key-value data is in key-value format. The controller codes the piece of compressed data to generate a first piece of compressed key-value data that is also in key-value format, and programs the first piece of compressed key-value data into the non-volatile memory.

摘要： A data storage device and method for operating a non-volatile memory including device based space allocation and host-based mapping table searching. In response to a write command from a host that indicates a write logical address in metadata in the write command, a controller at the device end determines a write physical address and allocates the non-volatile memory to provide a space to store write data at the write physical address. The controller transmits the write physical address to the host so the host can establish a mapping table on the host. When filling a completion queue in the host to inform the host of the finishing or completion of the write command, the controller also returns the write physical address to the completion queue for the host to update the mapping table on the host in real time. The metadata programmed at the device end is read back with the read data for read data verification at the host end. Commands may include write and read descriptors describing where to get the write data from a system memory of the host, or where to store the read data in the system memory of the host. The controller may return metadata read from different spaces of the non-volatile memory to the host to rebuild the mapping table. The non-volatile memory may be flash memory, and the controller may allocate the non-volatile memory for wear-leveling and garbage collection.

摘要： An apparatus and method for monitoring the power storage capability of a secondary power source of a data storage device is provided. A capacitor is used as a secondary power source. A charging path and a discharging path are selectively generated for the capacitor. After being charged through the charging path, the capacitor is then discharged through the discharging path while the charging path is disconnected from the capacitor. Then, the capacitor is checked to determine whether its voltage level has dropped below a threshold level and thereby an evaluation result obtained from evaluating the capacitor is generated.

摘要： The invention introduces a method for atomic writes in an SSD (Solid State Disk) system, performed by a processing unit, including at least the following steps. An atomic-write command instructing the processing unit to write first data whose length is less than a page length in a storage unit is received. When it is determined that the atomic-write command will trigger a cross-page buffering of a buffer, dummy data is filled into all available sub-regions of a first region of the buffer, and the first data is stored in a second region of the buffer. After the first data is successfully stored in the second region of the buffer, a safe pointer is modified to point to the end address of the last sub-region of the second region, which stores the first data.

摘要： Provided are a power failure protection method and solid state drive (SSD). The SSD comprises: a power-failure detection device, for monitoring in real time whether the power supply is abnormal; a power-failure protection device performs a power-failure protection operation when the power supply is monitored to be abnormal: breaking a connection with a host system bus, an SSD internal clock breaking from a system bus clock and writing data in the SSD cache into a storage unit of the SSD by using the SSD internal clock. The technical solution ensures completion of the data protection operations by utilizing a remaining capacity, thus ensuring data integrity.
