1416P ChipCorder from Information
Storage Devices (ISD). This is one of the
best of its kind on the market. It is a
complete solution in a single chip. It
doesn’t need external memory or
amplification and can be used with just
a microphone, a speaker and a few passive
components to make a complete
working voice memo recorder. The
memory in the chip is non-volatile
which means that recordings are
retained when power is removed. The
technology is E2PROM memory technology
(electrically-erasable programmable
read-only memory) but with an
interesting twist. Normally an E2PROM
cell stores a single digital bit of information
but in this chip the cells are
used as analogue storage. The charge in
a cell represents the analogue voltage
