Abstract
An electronic device includes a pulse generator, a signal synthesizer, and a first storage circuit. The pulse generator generates a mode active pulse and a mode pre-charge pulse in response to an operation mode signal. The signal synthesizer synthesizes an active signal and the mode active pulse to generate a synthesized active signal. The signal synthesizer synthesizes a pre-charge signal and the mode pre-charge pulse to generate a synthesized pre-charge signal. The first storage circuit performs an active operation, a read operation, or a pre-charge operation in response to the synthesized active signal, a read signal, and the synthesized pre-charge signal in each of a first read mode and a second read mode.
Claims18
An electronic device comprising:
- a pulse generator configured to generate a mode active pulse and a mode pre-charge pulse in response to an operation mode signal;
- a signal synthesizer configured to synthesize an active signal and the mode active pulse to generate a synthesized active signal and configured to synthesize a pre-charge signal and the mode pre-charge pulse to generate a synthesized pre-charge signal;
- and
- a first storage circuit configured to include a cell array and configured to perform an active operation, a read operation or a pre-charge operation in response to the synthesized active signal, a read signal and the synthesized pre-charge signal in each of a first read mode and a second read mode.
An electronic device comprising:
- a first storage circuit configured to output first data stored therein to a first input/output (I/O) line in response to a synthesized active signal and a read signal in each of a first read mode and a second read mode;
- a second storage circuit configured to output second data stored therein to a second I/O line in response to the read signal and an operation mode signal in the second read mode;
- and
- a selection/output circuit configured to output data loaded on the first or second I/O line in response to the read signal and the operation mode signal,
- wherein the synthesized active signal is enabled if an active signal is enabled or a mode active pulse is created, and wherein the mode active pulse is created in synchronization with a time that the operation mode signal is enabled.
An electronic device comprising:
- a first storage circuit configured to output first data stored therein to a first input/output (I/O) line in response to a read signal in each of a first read mode and a second read mode;
- a second storage circuit configured to output second data stored therein to a second I/O line in response to the read signal and an operation mode signal in the second read mode;
- and
- a selection/output circuit configured to output data loaded on the first or second I/O line in response to the read signal and the operation mode signal,
- wherein data loaded on the first I/O line are outputted through a data pad if the read signal is enabled in the first read mode, and wherein data loaded on the second I/O line are outputted through the data pad if the read signal and the operation mode signal are enabled in the second read mode.
