+.Nm mem ,
+.Nm kmem
+.Nd memory files
+.Sh DESCRIPTION
+The special file
+.Nm /dev/mem
+is an interface to the physical memory of the computer.
+Byte offsets in this file are interpreted as physical memory addresses.
+Reading and writing this file is equivalent to reading and writing
+memory itself.
+Only offsets within the bounds of
+.Nm /dev/mem
+are allowed.
+.Pp
+Kernel virtual memory is accessed through the interface
+.Nm /dev/kmem
+in the same manner as
+.Nm /dev/mem .
+Only kernel virtual addresses that are currently mapped to memory are allowed.
+.Pp
+On the
+.Tn pc532 ,
+physical memory is contiguous starting at address 0x00000000, EPROM starts
+at 0x10000000, and devices start at 0x28000000.
