LOW POWER DIGITAL DESIGN FOR DEEP SUBMICRON TECHNOLOGY
First Claim
1. An apparatus comprising:
- an implantable medical device including a storage circuit comprising;
a first stage circuit configured to receive an input signal and to invert and store a data bit received in the input signal;
a second stage circuit coupled to an output of the first stage circuit to invert and store a data bit received from the first stage circuit; and
an error circuit coupled to the output of the first stage circuit and an output of the second stage circuit, wherein the error circuit is configured to generate an error indication when the storage circuit outputs provide matching data bits while the first stage circuit and the second stage circuit are in an inactive state.

Abstract
An apparatus comprises an implantable medical device that includes a storage circuit. The storage circuit includes a first stage circuit configured to receive an input signal and to invert and store information about a data bit received in the input signal, a second stage circuit coupled to the output of the first stage circuit to invert and store information about a data bit received from the first stage circuit, and an error circuit coupled to the output of the first stage circuit and an output of the second stage circuit. The error circuit generates an error indication when the storage circuit outputs match while the first stage circuit and the second stage circuit are in an inactive state.

12. A method comprising:
-
storing, in a storage circuit of an implantable medical device, information to represent both an inverted version of a data bit and a non-inverted version of the data bit; disabling clocking of the storage circuit; and generating an error indication when the stored information to represent the inverted and non-inverted versions of the data bit match while the clocking is disabled. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
