  • Patent number: 9685220
    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.

  • Patent number: 8234541
    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.
