Abstract
A memory device includes: a set of input pads configured to receive from a source external to the memory device one or more input signals and a chip select signal; an operation circuit electrically coupled to the input pads, operation circuit configured to perform operations corresponding to the one or more input signals when the chip select signal is enabled; and an input management circuit electrically coupled to and between the input pads and the operation circuit, the input management circuit configured to control propagation of the one or more input signals based on the chip select signal.
Claims20
A memory device, comprising:
- a set of input pads configured to receive from a source external to the memory device one or more input signals and a chip select signal;
- an operation circuit electrically coupled to the input pads, the operation circuit configured to receive the one or more input signals via one or more input paths and perform operations corresponding to the one or more input signals when the chip select signal is enabled;
- and
- an input management circuit electrically coupled to and between the input pads and the operation circuit, the input management circuit configured to select based on the chip select signal (1) propagating the one or more input signals to the operation circuit or (2) preventing propagation of the one or more input signals over the one or more input paths.
A method of operating a memory device, the method comprising:
- receiving from a source external to the memory device one or more input signals and a chip select signal;
- controlling propagation of the one or more input signals based on the chip select signal, wherein controlling the propagation includes selecting based on the chip select signal (1) propagating the one or more input signals to an operation circuit or (2) preventing propagation of the one or more input signals over the one or more input paths;
- and
- performing operations corresponding to the one or more input signals when the chip select signal is enabled.
A method of manufacturing a memory device, the method comprising:
- providing a set of input pads configured to receive from a source external to the memory device one or more input signals and a chip select signal;
- providing an operation circuit configured to perform operations corresponding to the one or more input signals when the chip select signal is enabled;
- and
- electrically connecting an input management circuit between the input pads and the operation circuit, the input management circuit configured to select based on the chip select signal (1) propagating the one or more input signals to the operation circuit or (2) preventing propagation of the one or more input signals over the one or more input paths.
