Abstract
A semiconductor integrated circuit includes: a plurality of chips configured to receive an external voltage. Each one of the chips detects a signal delay characteristic of the one of the chips to generate an internal voltage having a level corresponding to the signal delay characteristic.
Claims19
A semiconductor integrated circuit comprising:
- a plurality of chips configured to receive an external voltage,
- wherein each one of the chips is configured to detect a signal delay characteristic of the one of the chips to generate an internal voltage having a level corresponding to the signal delay characteristic.
A semiconductor integrated circuit comprising:
- a first chip configured to operate an internal circuit block in accordance with a first internal voltage having a first level corresponding to a first signal delay characteristic;
- and
- a second chip configured to operate an internal circuit block in accordance with a second internal voltage having a second level corresponding to a second signal delay characteristic,
- wherein the first signal delay characteristic and the second signal delay characteristic are internally detected,
- wherein the first level of the first internal voltage changes based on a difference between a target signal delay characteristic and the first signal delay characteristic,
- wherein the second level of the second internal voltage changes based on a difference between the target signal delay characteristic and the second signal delay characteristic.
3 more elements
A semiconductor integrated circuit comprising a plurality of chips,
- wherein each one of the chips operates an internal circuit block, based on an internal voltage having an independent level corresponding to a signal delay characteristic of the chip, in order to compensate for a skew between output signals of the plurality of chips.
