Abstract
A semiconductor apparatus including a multichip package is disclosed. The semiconductor apparatus includes a slave chip having a slave region and a master region. The slave region is configured to have a first threshold voltage smaller than an operation voltage and the master region is configured to have a second threshold voltage greater than the operation voltage.
Claims9
A semiconductor apparatus comprising:
- a master chip including a first master region and a first slave region;
- a slave chip stacked on the master chip and including a second master region and a second slave region;
- and
- a voltage providing unit configured to set the first master region, the first slave region, and the second slave region to a first threshold voltage smaller than an operation voltage and set the second master region to a second threshold voltage greater than the operation voltage,
- wherein the voltage providing unit is configured to provide an operation bulk voltage to the first master region, the first slave region, and the second slave region, and a standby bulk voltage smaller than the operation bulk voltage to the second master region.
