Abstract
A semiconductor memory apparatus may include a bonding pad; a control signal pad; and an operation mode signal generation unit configured to generate a plurality of operation mode signals in response to a bonding signal inputted through the bonding pad and a control signal inputted through the control signal pad.
Claims17
A semiconductor memory apparatus comprising:
- a bonding pad;
- a control signal pad;
- and
- an operation mode signal generation unit configured to generate a plurality of operation mode signals in response to a bonding signal inputted through the bonding pad and a control signal inputted through the control signal pad,
- wherein the control signal is used in a normal operation of the semiconductor memory apparatus in a first input/output mode and but not used in the normal operation of the semiconductor memory apparatus in a second input/output mode or a wafer burn-in test mode, and
- the plurality of operation mode signals designate the first input/output mode, the second input/output mode and the wafer burn-in test mode.
