Sorry, but that means 8MB each.  The list is:

1M x 32 = 4MB
2M x 32 = 8MB
4M x 32 = 16MB
8M x 32 = 32 MB
16M x 32 = 64MB ...

The "x 32" part only means the "width" of the memory - 32 bits of data
with no parity (no hardware-based error checking).  If the spec says "x
36" then they would support parity - 32 bits of data and 4 bits to
record the parity.  The 2M indicates the "depth" of the memory - the
size of the chips used - 2 million bits.  The total size of the package
would be the size of each chip times the number of chips in the package.

Kingston has a document on their Web site called "The Ultimate Memory
Guide".  It might be useful to try to find it.  I got it from someone
else so I don't know exactly where to find it.
