The "No-Power" Required Memory

Our digital camera accepts an "SD", which means I know not, nor do I know or understand how it works. Our first D.C. had no such capability, stored only 7 images, maximum, and promptly LOST those, if batteries crapped out.

Our new one stores many more, in the SD, even if batteries are removed. I studied Electronics Engineering 1961-'63. We then knew of "memory" of various kinds, but ALL depended upon a remaining power source, i.e., a battery, to retain memory. Evidently, some sort of unimaginable, to me, development, has allowed non-powered memory retainment.

Lately, I hear the term, "flash memory". Is that it? How does it work, anybody? I gotta know! This imp incomplete if unknowing. :( imp
 

SD Cards store more pictures on your camera..They normally fit into a slot near or next to the battery..They can be removed and plugged into your computer/laptop/printer to recover the pictures..You can also take the card to a photo shop (Walmart) and have pictures printed..Check your paperwork, that came with the camera, to see where and what card you need..
 
Thank you, Ken! imp
 

Batteries never retain memory, it's all on the card. The more capacity of the card, the more pics. I have 32 gigs of memory in my camera which makes sure I can run a long video.
