Abstract
A semiconductor memory device having a status register read function includes a plurality of data output pads electrically connected to corresponding package pin, and a swap controller connected between the plurality of data output pads and a plurality of output lines that output memory-related unique information in a specific operation mode. The swap controller controls a swap according to preset swap program information when a swap is needed to match the data output pads to the package pins.
Claims10
A semiconductor memory device, comprising:
- a plurality of data output pads to be electrically connected to corresponding package pins in a packaging process;
- and
- a swap controller connected between the plurality of data output pads and a plurality of output lines that output memory-related unique information in a specific operation mode, the swap controller configured to control a swap according to preset swap program information when a swap is needed to match the data output pads to the package pins.
A method of swapping data output pads of a semiconductor memory device having a status register read function to match package pins, the method comprising:
- comparing an arrangement of the data output pads with an arrangement of package pins to be electrically connected to the data output pads in a packaging process;
- and
- swapping the data output pads on the basis of the package pins to match the data output pins with the package pins in response to the comparison result.
