用于校正存储器错误的共享的奇偶校验
Abstract:
示例包括用于在存储器控制器和存储器设备之间实现读取和写操作的技术。在实施例中，存储器控制器被配置为接收数据位以写入存储器设备，使用存储器控制器ECC元件和数据位，确定多个存储器控制器ECC校验位和一个或多个奇偶校验位，以将存储器控制器ECC校验位和一个或多个奇偶校验位附加到数据位，并在写操作期间将数据位、存储器控制器ECC校验位和一个或多个奇偶校验位发送到存储器设备。在实施例中，存储器控制器被配置为从存储器设备接收数据位和存储器控制器ECC校验位，针对存储器控制器ECC校验位来检查数据位并校正检测到的错误，并在读操作期间返回数据位。
Abstract(English):

Examples include techniques for implementing read and write operations between a memory controller and a memory device. In an embodiment, the memory controller is configured to receive data bits to write to the memory device, to determine, using a memory controller ECC component and the data bits, a plurality of memory controller ECC check bits and one or more parity bits, to append the memory controller ECC check bits and the one or more parity bits to the data bits, and to send the data bits, the memory controller ECC check bits, and the one or more parity bits to the memory device during awrite operation. In an embodiment, the memory controller is configured to receive the data bits and the memory controller ECC check bits from the memory device, to check the data bits against the memory controller ECC check bits and correct errors detected, and to return the data bits during a read operation.
