Semiconductor memory device and method of operating the same |
摘要 |
A semiconductor memory device including semiconductor memory cells with at least one memory cell capable of either acting as a storage device for ECC information or of acting as a redundant memory cell is provided. The semiconductor memory device further includes a signal control device for signaling if the at least one memory cell is to be used either as a storage device or as a redundant memory cell. A method of operating a semiconductor memory device is also provided including the steps of registering a status of a signal device and, depending on the status of the signal device, operating the at least one memory cell either as a storing device for ECC information or as a redundant memory cell.
