Abstract
An integrated circuit (IC) device configured for multiple return material authorizations (RMAs) is provided. The IC device includes an asset and a return material authorization (RMA) counter fuse including a first fuse, a second fuse, and a third fuse. The IC device enters an RMA state in response to blowing the first fuse, a second state in response to blowing the second fuse, and the RMA state in response to blowing the third fuse.
Claims20
An integrated circuit (IC) device configured for multiple return material authorizations (RMAs), the IC device comprising:
- an asset disposed on the IC device;
- and
- a return material authorization (RMA) counter fuse comprising a first fuse, a second fuse, and a third fuse, wherein the IC device enters an RMA state that disables access to the asset in response to blowing the first fuse, wherein the IC device enters an OWNED state in response to blowing the second fuse, wherein the IC device blows the second fuse during a time period beginning after the first fuse is blown, and wherein the third fuse is blown during a time period beginning after the first fuse is blown.
A tangible, non-transitory, and machine-readable medium comprising machine-readable instructions that, when executed by one or more processors of an integrated circuit (IC) device, cause the one or more processors to perform operations comprising:
- receiving a first command to blow a first fuse on the IC device;
- blowing the first fuse, wherein blowing the first fuse disables access to one or more assets on the IC device and causes the IC device to enter an RMA state;
- receiving a second command to blow a second fuse on the IC device;
- blowing the second fuse during a time period beginning after the first fuse is blown, wherein blowing the second fuse enables access to the one or more assets on the IC device and causes the IC device to leave the RMA state and enter an OWNED state, wherein the IC device is configured to receive an additional one or more assets in the OWNED state;
- receiving a third command to blow a third fuse on the IC device;
- and
- blowing the third fuse, wherein blowing the third fuse disables access to the one or more assets on the IC device and causes the IC device to re-enter the RMA state.
A method for configuring an integrated circuit (IC) device for multiple Return Material Authorizations (RMAs), the method comprising:
- receiving a first command to blow a first fuse on the IC device;
- blowing the first fuse, wherein blowing the first fuse disables access to one or more assets on the IC device and causes the IC device to enter an RMA state;
- receiving a second command to blow a second fuse on the IC device;
- blowing the second fuse during a time period beginning after the first fuse is blown, wherein blowing the second fuse enables access to the one or more assets on the IC device and causes the IC device to enter an OWNED state;
- receiving a third command to blow a third fuse on the IC device;
- and
- blowing the third fuse, wherein blowing the third fuse disables access to the one or more assets on the IC device and causes the IC device to re-enter the RMA state.
