Systems and methods suitable for assisting data storage on a solid-state mass storage device by furthering interaction between a host and the solid-state mass storage device. The method includes providing data in a target block from a solid-state mass storage device to a host computer system, analyzing the data to identify valid and invalid data of the data in the target block with the host computer system, removing the invalid data, reformatting the valid data into a new data structure with the host computer system, writing the new data structure to the mass storage device, and marking the data in the target block as invalid.

Systems and methods are provided for initiating wear leveling on block-aligned boundaries for non-volatile memories (“NVMs”), such as flash memory. In some embodiments, an electronic device including the NVM may suspend the programming of data upon reaching the end of a dynamic block. The electronic device may then perform wear leveling on a low-cycled block of the NVM. The electronic device may thus be configured to copy static data from the low-cycled block to another block of the NVM. After wear leveling has completed, the memory interface can program a second portion of the data to a new dynamic block of the NVM. This way, the electronic device can improve the efficiency of garbage collection. In addition, the electronic device can decrease the programming time for user generated writes, the wearing of the NVM, and overall power consumption.

A data writing method, and a memory control circuit unit and a memory storage apparatus using the method are provided. The method includes: grouping the logical units into a first area and at least a second area according to the write counts of the logical units configured on the memory apparatus. The method also includes: determining whether the logical unit corresponding to the received data belongs to the first area. The method further includes: if the logical unit corresponding to the received data belongs to the first area, programming the received data into a first active physical erasing unit, and if the logical unit corresponding to the received data belongs to the first area, programming the received data into a second active physical erasing unit. Accordingly, the method may improve the efficiency of a garbage collection operation.

The invention discloses a mechanism for double-truck butt joint and garbage transfer of garbage trucks. The mechanism comprises a carriage lifting and horizontally-moving mechanism, a garbage pushing mechanism, a garbage waster water pumping mechanism and a butt joint sealing mechanism. The carriage lifting and horizontally-moving mechanism is used for lifting and horizontally moving carriages of small and medium-sized garbage collection trucks so as to be in butt joint with a tail carriage of a large garbage transfer truck. In the garbage transfer process, the garbage pushing mechanism pushes garbage in the carriages of the small and medium-sized garbage collection trucks in butt joint to the carriage of the large garbage transfer truck and compresses the garbage. The garbage waster water pumping mechanism pumps waste water in waste water boxes of the small and medium-sized garbage collection trucks to a garbage waste water box of the large garbage transfer truck in the double-truck butt joint process. The butt joint sealing mechanism at the tail carriage of the truck is located between the carriages of the small and medium-sized garbage collection trucks and the tail carriage of the large garbage transfer truck for sealing. The mechanism has the advantages of being simple and compact in structure, good in operability, high in operation efficiency, and capable of reducing the number of garbage transfer stations which are smelly and dirty in urban areas, and the like.

The invention relates to an indoor hydraulic self-closing-opening type waste collecting bracket device. The indoor hydraulic self-closing-opening type waste collecting bracket device comprises a base,a supporting pipe is arranged on the base, a piston is arranged in the supporting pipe, a space above the piston constitutes a pressurized liquid space, a piston rod is arranged at the bottom of thepiston, and the top end of the supporting pipe communicates with a ring-shaped hose through a joint in a sealing mode. The outer portion of the ring-shaped hose is covered with a bag mouth supportingpart. A second hook connector is arranged on the one side, near the supporting pipe, of the bag mouth supporting part. A first hook connector is arranged on the other side, opposite to the supportingpipe, of the bag mouth supporting part. The bottom of the first hook connector is connected with an auxiliary supporting column part. The top of the auxiliary supporting column part can move downwardsobliquely in the direction of being away from the support pipe and can drive the bag mouth supporting part to close to form a linear closed structure. A hydraulic driving device is arranged in the base, and a sensor is arranged on the side wall of the base. The indoor hydraulic self-closing-opening type waste collecting bracket device increases the function of automatic closing the garbage bag mouth, avoids peculiar smell diffusion, improves the environmental protection performance and reduces the cost.

A non-volatile memory (NVM) apparatus and a garbage collection method thereof are provided. The NVM apparatus includes a NVM and a controller. The controller is coupled to the NVM. The controller accesses the NVM according to a logical address of a write command of a host. The controller performs the garbage collection method to release space occupied by invalid data. The garbage collection method includes: grouping a plurality of blocks of the NVM into a plurality of tiers according to hotness of data, moving valid data in one closed source block of a hotter tier among the tiers to one open target block of a cooler tier among the tiers, and erasing the closed source block of the hotter tier to release space.
