I have been looking at RAM modules for a hobby project, and I couldn't find out what "256k x 8", or "16M x 8" meant. Googling such things simply gave me a bunch of parts. So, my question is, what do these numbers mean? Seeing as I learn best from example, what would you call RAM with an 8bit address, and 8 bit words? Or the same with 16 bit words?

Thankyou in advance.
Joe.

256k x 8 means 262,144 addressable locations, each with 8 bits of data.

That is 18 address lines, and 8 data lines.

it is also 2 megabits


I would call memory with 8 address lines and 8 bit words... Obsolete.

You may have to get something larger and pull the unused address lines to ground (to force them to zeros)
