Abstract: There are provided a DDR controller, a method for implementing the same and a chip, which are applicable to the field of DDR controller technology. The method includes the steps of: parsing a plurality of buffered commands concurrently (S501); prejudging relationships between a bank and a row of an address to be accessed by each parsed command and a bank and a row of an address for a currently executed command; and transmitting a PRECHARGE command and an ACTIVE command in advance. With the above technical solution, the PRECHARGE command and ACTIVE command which should have been transmitted serially can be transmitted in advance by being hidden in parallel in a Read or WRITE period to thereby make full use of a bandwidth of a DDR device.

Abstract: An allocation method comprises: partitioning moderate memory into a plurality of physical memory pages having predetermined page size according to the predetermined page size; scanning the moderate memory using the predetermined page size and recording the physical address and damage degree of each physical memory page; obtaining the allocation information of the physical memory pages when a memory request is received and allocating physical memory to the request based on the recorded physical address and damage degree of each physical memory page and the obtained allocation information. A moderate memory is scanned and the physical address and damage degree of each physical memory page are recorded, then the physical memory is allocated based on the recorded physical address and damage degree of each physical memory page and the obtained allocation information.

Abstract: The present invention is applicable to the field of electrics and provides an integrated circuit (IC) and a standby controlling method thereof. The IC comprises a reset device, a standby control device, a functional device and a power supply control device. The functional device at least comprises a functional unit that does not operate in a standby mode. The power supply control device is configured to supply power to the functional device, the standby control device and the reset device.

Abstract: A method for controlling access to data in a Flash is provided, including steps as follows: outputting at least one main data block to a buffer area of the Flash continuously, the buffer area of the Flash being adapted to buffer data to be inputted to a storage area of the Flash; generating and buffering checksum data for each main data block while outputting the at least one main data block; and outputting the buffered checksum data of the at least one main data block to the buffer area of the Flash. Another method for controlling access to data in the Flash, apparatuses corresponding to the methods and methods for controlling data access by a controller are also provided. The efficiency of data access in the Flash is raised.
