+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for generic memory module Serial Presence Detect.
+During kernel boot it displays module type, and where possible, the size and
+rated speed of the memory module.
+Additional information such as bank configuration and width is
+printed if the kernel is booted in verbose mode.
+.Pp
+The Serial Presence Detect data for each memory module is also made accessible
+to user mode via
+.Xr sysctl 8 .
+An entry for each
+.Nm
+device is created under the
+.Dv hw
+top-level MIB.
+.Pp
+Some SPD ROMs also have a temperature sensor.
+It's supported by
+.Xr sdtemp 4 .
