Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
76 words
An integrated circuit device, comprising: a bond pad selectively connectable to a first voltage source corresponding to a first option of the device and coupled to a second voltage source corresponding to a second option of the device, wherein the device operates in the second option when the bond pad is unconnected to the first voltage source and the device operates in the first option when the bond pad is connected to the first voltage source.
Claim 2
Dependent Claim
22 words
An integrated circuit device as claimed in Claim 1 and wherein a transistor couples the bond pad to the second voltage source.
Claim 3
Dependent Claim
39 words
An integrated circuit device as claimed in any preceding claim and including option circuitry, responsive to voltage, to operate the device in a first mode corresponding to a first option and a second mode corresponding to a second option.
Claim 4
Dependent Claim
35 words
An integrated circuit device as claimed in claim 3 and further comprising: a latch having an input coupled to the bond pad and an output for transmitting a signal in dependence upon bond pad connection.
Claim 5
Dependent Claim
22 words
An integrated circuit device as claimed in any preceding claim and wherein said first and second options are options of semiconductor memory.
Claim 6
Dependent Claim
35 words
An integrated circuit device as claimed in claim 5 and wherein the first option configures the memory device as a X 1 memory and the second option configures the memory as a X 4 memory.
Claim 7
Dependent Claim
37 words
An integrated circuit devices as claimed in Claim 5 and wherein the first option configures the memory device to have a 4,096 cycle refresh, and the second option configures the device to have a 2,048 cycle refresh.
Claim 8
Dependent Claim
94 words
An integrated circuit device as claimed in any of claims 5 to 7 in that they depend from claim 4 and including an array of memory cells; support circuitry to read information from the memory cells and write information to the memory cells; wherein the option circuitry operates the array and support circuitry in the first mode when the bond pad is unconnected to the first voltage source and wherein the option circuitry operates the array and support circuitry in the second mode when the bond pad is connected to the first voltage connected.
Claim 9
Dependent Claim
26 words
An integrated circuit device as claimed in any preceding claim wherein at least one of said first and second voltage sources is generated within the circuit.
Claim 10
Independent Claim
47 words
A method for option selection for an integrated circuit device; comprising the steps of: coupling a bond pad to a first voltage to operate the device in a first mode; and coupling the bond pad to a second voltage to operate the device in a second mode.
Claim 11
Dependent Claim
19 words
A method as claimed in claim 9 and wherein said coupling is by means of bonding the bond pad.
Claim 12
Dependent Claim
28 words
A method as claimed in claim 10 and wherein said coupling is by means of a scheduled bonding step in production of a device of the second option.
