Abstract
An integrated circuit of a multiple die package structure having a plurality of semiconductor devices, each of the plurality of semiconductor devices may include an active termination circuit configured to perform an active termination operation to the semiconductor device, and to be turned off in a disable state of an active termination setting code, a multiple die package information transfer unit configured to transfer a multiple die package information signal, and a compulsory termination unit configured to selectively convert the active termination setting code into the disable state in response to the multiple die package information signal.
Claims12
An integrated circuit of a multiple die package structure having a plurality of semiconductor devices, each of the plurality of semiconductor devices comprising:
- an active termination circuit configured to perform an active termination operation to the semiconductor device, and to be turned off according to a disable state of an active termination setting code;
- a multiple die package information transfer unit configured to transfer a multiple die package information signal;
- and
- a compulsory termination unit configured to selectively convert the active termination setting code into the disable state in response to the multiple die package information signal.
An operation method of each of a plurality of semiconductor devices included in an integrated circuit of a multiple die package structure, wherein each of the plurality of semiconductor devices includes an active termination circuit that performs an active termination operation to the semiconductor device and is controlled by an active termination setting code, the operation method comprising:
- determining an enable state of a multiple die package information signal;
- turning off the active termination circuit by converting the active termination setting code into a disable state, if the multiple die package information signal is enabled;
- performing the active termination operation according to the active termination setting code, if the multiple die packaging information signal is disabled.
