    • A Not and Flash (Nandflash) controller and a data transmission method with the Nandflash controller are provided. The Nandflash controller includes a parameter configuration device, configured to receive an operation command from outside, wherein the operation command indicates a current transmission type, execution times needed for transmitting data of size of a buffer in the Nandflash, and command parameters used by each execution; a transmission controlling device, configured to transmit data of a precoded size with the Nandflash during each data transmission according to the current transmission type and the command parameters used by this execution, until completing the execution times. The controller and method advantageously avoid configuring a command for the next operation each time the data of the precoded size is transmitted, save time and clock resources, and greatly improves transmission efficiency.
    • 提供了非闪存(Nandflash)控制器和Nandflash控制器的数据传输方法。 Nandflash控制器包括参数配置设备,配置为从外部接收操作命令,其中操作命令指示当前传输类型,在Nandflash中发送缓冲区大小的数据所需的执行时间,以及由每个执行使用的命令参数 ; 发送控制装置,被配置为根据当前的发送类型和由该执行使用的命令参数在每个数据发送期间发送具有Nandflash的预编码大小的数据,直到完成执行时间为止。 控制器和方法有利地避免了在每次传输预编码大小的数据时节省下一次操作的命令,节省了时间和时钟资源,并大大提高了传输效率。
