本发明的一个实施例提供了一种系统，当在存储操作期间仅更新行的一部分时，该系统更新行的纠错码。系统通过接收存储操作来操作，其中存储操作包括要存储到线的部分的新数据以及线的部分的地址。接下来，系统从该地址读取该行的该部分的旧数据，然后将新数据存储到该行的该地址处的该部分。系统还更新该行的现有纠错码以反映新数据。这涉及根据现有的纠错码、旧数据和新数据来计算该线路的新纠错码。然后，系统用新的纠错码替换现有的纠错码。
One embodiment of the present invention provides a system that updates an error-correcting code for a line when only a portion of the line is updated during a store operation. The system operates by receiving the store operation, wherein the store operation includes new data to be stored to the portion of the line, as well as an address of the portion of the line. Next, the system reads old data for the portion of the line from the address, and then stores the new data to the portion of the line at the address. The system also updates the existing error-correcting code for the line to reflect the new data. This involves calculating a new error-correcting code for the line from the existing error-correcting code, the old data and the new data. The system then replaces the existing error-correcting code with the new error-correcting code.
