This is a 1kb(1024 bit) ram its data width is 1 bit 

this is inside of the 1x1kb RAM

this is how the 1x4bit RAM looks like

sry if this looks bad this was my first time uploading on itch 

I will answer some questions if possible

edit:

b = bit

BT = byte

sry my error it is not a 1kb memory ram its only 1/8 of it, but it should be possible to easily create 1kb with this by either making the width 8 or making the adress line 14

1kb = 8000 bit for those that don't know
