SDRAM (U21, U22) data/address/control line to the A5 chip Try to get the line of isometric, are not more than 3 cm
A5 G3, J5 two feet, can not be connected to the nearest
To ensure both into two pieces of SDRAM 38 feet line of equal length
FLASH (U20) to the A5 attachment length difference can be relaxed
But the difference to control under 10 cm
