===== Random notes =====

Flash
	24 + 32 horizontal = 56 on bottom x 32 on side = 1792 unit cells
	Actual flash capacity is 2048 14-bit words = 28672 bits so each unit cell = 16 bits. 4x4?

SRAM
	4 columns of 8 bits each
	32 rows
	Horizontal WLs
	Vertical BLs
	
	5 bit row address bus
	2 bit col address bus
	
EEPROM
	256 bytes
	16 horizontal x 16 vertical = 256 unit cells
	Seems to be some dummy bits?
