Abstract
A semiconductor apparatus may include a degradation detection circuit and a circuit block. The degradation detection circuit may detect a degradation occurred in a semiconductor apparatus and generate degradation information. The circuit block may include at least one transistor configured to receive a variable bias voltage and a variable gate voltage.
Claims17
A semiconductor system comprising:
- a memory apparatus configured to detect degradation that has occurred in the memory apparatus and generating degradation information based on a training command, and generate a variable bias voltage and a variable gate voltage based on a voltage setting command;
- and
- a memory controller configured to provide the training command to the memory apparatus, and generate the voltage setting command based on the degradation information.
A semiconductor system comprising:
- a memory apparatus including a plurality of ranks, and configured to generate a degradation information by detecting degradation that has occurred in the plurality of ranks based on a training command;
- and
- a memory controller configured to perform memory mapping by mapping a rank which is degraded more than a reference among the plurality of ranks with a rank which is degraded less than the reference among the plurality of ranks, based on the degradation information.
