First, let's have a look at this memory module:

Filename

File size

Fair use/fair dealing exception

4217400 = 4M x 4
two such chips = 4 MByte

HM514100 = 4M x 1
so it's 4 Mbit parity

In general, a perfectly normal SIMM of 4 MB with parity.

But suddenly, I've encountered this one:

simm2.jpg
Filename

Fair use/fair dealing exception

KM44C4100 = 4M x 4
two such chips = 4 MByte

HYB511000 = 1M x 1
so it would be only 1 Mbit parity

Does it make any sense?
Am I missing something?
Are such modules supposed to work with typical boards?

That doesn't make sense, there's only one parity bit for every 4 addresses... I expect those sticks will not work with a normal board that expects every address to have a parity bit.
