    Abstract: A method and apparatus are provided for implementing enhanced vertical ECC storage in a dynamic random access memory. A dynamic random access memory (DRAM) is split into a plurality of groups. Each group resides inside a DRAM row address strobe (RAS) page so that multiple locations inside a group can be accessed without incurring an additional RAS access penalty. Each group is logically split into a plurality of segments for storing data with at least one segment for storing ECC for the data segments. For a write operation, data are written in a data segment and then ECC for the data are written in an ECC segment. For a read operation, ECC are read from an ECC segment, then data are read from the data segment.

    Abstract translation: 提供了一种用于在动态随机存取存储器中实现增强的垂直ECC存储的方法和装置。 动态随机存取存储器(DRAM)被分成多个组。 每个组都驻留在DRAM行地址选通(RAS)页面中,从而可以访问组内的多个位置,而不会引起额外的RAS访问损失。 每个组在逻辑上分成多个段,用于存储具有用于存储数据段的ECC的至少一个段的数据。 对于写入操作,将数据写入数据段,然后将ECC用于数据写入ECC段。 对于读取操作,从ECC段读取ECC,然后从数据段读取数据。
