May 2008 Slide Doc: IEEE 802.15-08-0000-00-0ban SooHwan, YangMoon, SungHyup (KORPA) and DoHyeun Kim (Cheju National University) How can keep information and suppress EMC 8 E-ink can memory its state “Memory” doesn’t mean memory ICs It keeps its state without electric resource Although it is not connected, you can keep information until you refresh data. During “Keeping time”, EMC problem never happen because it is turned off
