Hi all, I am looking at making a data logger which will require a lot of non-volitile RAM about 256-512 kbytes (8bit byte) and preferrably serial. Does any one have any suggestions? Atmel have a chip which is serial 4 megabit which has 2048 pages of 264 bytes x 8 bits whick looks fine but because the pages are 264 bytes does that mean that I have to write to it page at a time. In the data sheet it decribes eraseing the page before writing to an address, so could I write 16 bytes to a page of 264 without eraseing the whole page? Regards Jason.
