Canon LC-MEMO

Dismantling the LC-MEMO reveals indeed a chipset manufactured by Toshiba, too. The original T3690 was replaced with the T3721 in the Canon product, but the memory chip was kept. The T3691 stores a maximum of 21 information items in units of 8 alphabetical characters and 12 numerals each. If you add the bits together you end with a total amount of 2048 bits or 256 bytes.
