POSH memory

Hello, once again, everyone!
Today I'm presenting what I believe to be the FIRST hard-drive built in Minecraft: POSH!

POSH stands for:

Portable: You can move the memory very easily, with no moving of wires, only blocks!
Ordered: Honestly, this was just a place holder...but, since the memory is in order, in kind of works, right? :/
Serial: The data is transmitted serially (To nowhere in this project, but if you ever implement this, it would transmit serially through the dock to wherever it's needed) every time you write to memory.
Hard-drive: It's memory is stored physically, in block positions.

It's a machine that is used for the transferring of data between computers, or for storing data outside of a computer. So, it's kind of like a flash drive memory stick. I'm working on making this more feasible for usage in computers, because at the moment, it's huge. Each byte of data takes up an enormous area.

This machine works basically like this:

The output of the POSH get's XOR'd with the write inputs, then AND'd with the write button. That then leads into a monostable Toggle Flip Flop, which makes the memory pin (gold block) change position. This basically makes a TFF into a Data Flip Flip, therefore making a DFF with physical memory.
When ejected, the memory pins get pushed out 1 block, allowing for moving with WorldEdit. Once you "plug" it back in, turn the eject lever back off to allow for the alteration of memory by lever.
