Abstract
A refresh control device, and a memory device may be provided. The latch controller may include a first oscillator configured to generate a first oscillation signal, and a second oscillator configured to generate a second oscillation signal. The latch controller may be configured to receive a precharge signal and prevent the second oscillation signal from being synchronized with the precharge signal.
Claims12
A refresh control device comprising:
- a first oscillator configured to generate a first oscillation signal;
- a second oscillator configured to generate a second oscillation signal;
- a counter configured to generate a pre-enable signal synchronized with the first oscillation signal based on a precharge signal;
- a binary code generator configured to generate a random binary code signal formed in a random pulse shape based on the second oscillation signal;
- and
- a combination circuit configured to output a latch enable signal based on the random binary code signal and the pre-enable signal.
