Open the CIPO recordAbstract From the Canadian patent
A cardiac stimulator (10) having a memory device (50) particularly useful in size-constrained electronic products, such as cardiac stimulators. To provide additional memory for such size-constrained products memory chips (50A, 50B, 50C, 50D) are stacked one on top of another. The memory chips are configured to facilitate bonding without crossed contacts using aligned bonding pads, vias, or castellations. Each memory chip also includes an address selection circuit that receives signals from one or more address lines to selectively enable and disable the memory chips in the stack.

Why it's free to use
- Filed July 21, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 21, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 21, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
