    • A flash memory device includes a flash memory, a buffer memory and a control unit. The buffer memory temporarily stores data that is to be stored in the flash memory or data that is read from the flash memory. The control unit includes a buffer controller. The buffer controller performs a jump operation for transferring data unnecessary to be updated in the flash memory to an adjacent position of update data in the buffer memory when a size of data necessary to be updated in the flash memory is smaller than a size of a block of the flash memory. Therefore, the flash memory device and a flash memory system including the flash memory device may simplify an update operation with a DMA operation and a performance of a system is enhanced.
    • 闪存器件包括闪速存储器,缓冲存储器和控制单元。 缓冲存储器临时存储要存储在闪速存储器中的数据或从闪存读取的数据。 控制单元包括缓冲器控制器。 当需要在闪存中更新的数据的大小小于块的大小时,缓冲器控制器执行跳转操作,用于将闪存中不必要更新的数据传送到缓冲存储器中的更新数据的相邻位置 的闪存。 因此,闪速存储器件和包括闪速存储器件的闪存系统可以通过DMA操作来简化更新操作,并提高系统的性能。

    • An Error Correcting Code (ECC) control circuit in a memory controller includes an ECC controller configured to receive data from a memory device in response to a request from a host device. The ECC controller transmits the data to a direct memory access (DMA) buffer for transfer to the host device, and to an ECC block for error detection and correction of the data. The ECC controller is configured to interrupt transmission of the data to the DMA buffer and transmit error-corrected data output from the ECC block to the DMA buffer responsive to detection of an error in the data by the ECC block. Related systems and methods are also discussed.
    • 存储器控制器中的错误校正代码(ECC)控制电路包括ECC控制器,其被配置为响应于来自主机设备的请求从存储器设备接收数据。 ECC控制器将数据发送到用于传送到主机设备的直接存储器访问(DMA)缓冲器,以及用于错误检测和数据校正的ECC块。 ECC控制器被配置为响应于ECC块对数据中的错误的检测,中断数据到DMA缓冲器的传输并将从ECC块输出的错误校正数据传送到DMA缓冲器。 还讨论了相关系统和方法。
