2048 cell single chamber FRAM. In this demo random values are written to random addresses. Scales pretty well as the more important addressing mechanisms are designed to use constant space rather than logarithmic. *** Added link to the R216K2A.

    @The8BitPotato 7.4 kB if you count 29 bits per cell, but practically in terms of processor design, the most that will be accessible/addressible is 16 to 24 bits for data, hence 4 kB and 6 kB respectively.

    Well, it's scalable. You could build a 256x256 one, it wouldn't care. I built one with 2048 cells because that's how much I needed.

    P.S.: I just pulled up the Calculator program, and wow! 7.4 kilobytes in TPT!

    Subframe technology is just mind-blowing. It's almost impossible for me to imagine anything in TPT going this fast!! It must be pretty difficult to design these.

    It's a Random Access Memory made of FILT. Delving into it deeper, it's Random Access because you read/write any cell whenever you want. That's not the case with Sequential Access Memory, which needs to be rewinded and such (for example audio tapes).

    Huh... im still not sure how it works... but it looks pretty :)

    It means that, unlike my previous FRAMs (or any other FRAM on TPT for that matter), it has only a single block of space dedicated to reading/writing data. Take my previous FRAM, for example. It has two blocks, one of which is the storage and the other is where *some* of the reading/writing happens. That means that for 1024 cells of storage you'd have to sacrifice 2048 pixels. In my first computer, there were 4 blocks (lol).
