Abstract
A serial presence detect (SPD) device includes a region of nonvolatile memory for SPD data and an additional region for other (e.g., vendor) use. The additional region may be subdivided into write protect regions that can be individually and independently write protected. To configure the write protection, a password key scheme is used to enter a mode whereby the write protection attributes may be configured. Another password key scheme is used to exit the write protection configuration mode.
