Abstract: A bridge control chip includes a first interface, a second interface, and a processor, wherein the first interface is coupled to a host device, the second interface is coupled to a memory device, and the memory device is a flash memory device. The processor is arranged to execute commands in a queue in sequence, to transmit the commands in the queue to the memory device through the second interface in sequence, wherein when the processor receives one or more received commands from the host device, the processor sorts the one or more received commands and commands which are currently and temporarily stored in the queue according to a distance between a logical address of each of the one or more received commands and a logical address of a current command in the queue that is currently executed by the processor.

Abstract: The invention is related to a non-transitory computer program product, a method and an apparatus for controlling access to a flash storage. The method, performed by a processing unit of a bridge integrate circuit (IC), includes: receiving a host write command from a host side; determining whether the flash storage needs to enter a hibernate state based on at least information regarding a length of data that has been programmed into the flash storage and/or a quantity of host write commands that have been executed after executing the host write command; and instructing the flash storage to enter the hibernate state when the length of data and/or the quantity of host write command meets a triggering condition.

Abstract: The invention is related to a non-transitory computer program product, a method and an apparatus for controlling access to a flash memory card. The method, performed by a processing unit of a bridge integrate circuit (IC), includes: determining whether a temperature of a motherboard has exceeded a threshold through a temperature sensor IC after receiving a host read or write command from a host side; requesting a flash memory card to enter a sleep state when the temperature of the motherboard has exceeded the threshold; and instructing the flash memory card to perform an operation corresponding to the host read or write command when the temperature of the motherboard hasn't exceeded the threshold. The bridge IC and the temperature sensor IC are disposed on the motherboard, the flash memory card is inserted into a card slot on the motherboard, and the bridge IC is coupled to the temperature sensor IC and the flash memory card through a circuit of the motherboard.
