Abstract
Exemplary embodiments disclose a command control circuit including a command decoder configured to generate an internal command signal using a chip select (CS) signal and a command signal, and a CS gating logic configured to provide the CS signal to the command decoder, wherein the CS gating logic is further configured to provide the CS signal to the command decoder in response to a clock enable (CKE) signal being at a first level, and block the CS signal from the command decoder in response to the CKE signal being at a second level.
Claims20
A command control circuit comprising:
- a command decoder configured to generate an internal command signal using a chip select (CS) signal and a command signal;
- and
- a CS gating logic configured to provide the CS signal to the command decoder,
- wherein the CS gating logic is further configured to provide the CS signal to the command decoder in response to a clock enable (CKE) signal being at a first level, and block the CS signal from reaching the command decoder in response to the CKE signal being at a second level.
A command control circuit comprising:
- a command decoder configured to generate an internal command signal;
- and
- a CS gating logic configured to gate a CS signal using a CKE signal and providing the gated CS signal to the command decoder,
- wherein the command decoder is enabled in response to the gated CS signal being at a first level, and is disabled in response to the gated CS signal being at a second level.
A method of a command control circuit, the method comprising:
- receiving a chip select (CS) signal, a command signal, and a clock enable (CKE) signal;
- generating an internal command signal based on the CS signal and the command signal in response to the CKE signal being at a first level;
- and
- blocking the internal command signal from being generated in response to the CKE signal being at a second level.
