Abstract
An integrated circuit memory is capable of storing analog information without the need for A/D conversion. Samples of a analog signal input are stored in nonvolatile memory cells. The integrated circuit is also capable of storing digital information in digital form. The sampling rate at which the analog signal input is sampled is user selectable. An internal signal path of the integrated circuit memory is differential, which enhances the precision with which the analog signal is stored in the memory cells.
