摘要: A memory card, connected to a host, includes a NAND flash memory and a memory controller. The NAND flash memory includes multiple pages, and each page includes multiple sectors. The memory controller receives sector data and a corresponding sector address from the host. The memory controller enables the sector data to be transferred to the NAND flash memory over a first data bus, via a buffer memory, when the sector address is an address for accessing a first sector in a selected page. The memory controller enables the sector data to be transferred to the NAND flash memory over a second data bus, bypassing the buffer memory, when the sector address is an address for accessing a sector other than the first sector in the selected page.
摘要翻译: 连接到主机的存储卡包括NAND闪存和存储器控制器。 NAND闪存包括多个页面,并且每个页面包括多个扇区。 存储器控制器从主机接收扇区数据和对应的扇区地址。 当扇区地址是用于访问所选择的页面中的第一扇区的地址时,存储器控制器使得扇区数据能够经由缓冲存储器通过第一数据总线传送到NAND快闪存储器。 当扇区地址是用于访问所选页面中的第一扇区之外的扇区的地址时,存储器控制器使扇区数据能够通过第二数据总线传送到NAND闪速存储器,绕过缓冲存储器。
