Abstract
Apparatuses and methods for setting a duty cycler adjuster for improving clock duty cycle are disclosed. The duty cycle adjuster may be adjusted by different amounts, at least one smaller than another. Determining when to use the smaller adjustment may be based on duty cycle results. A duty cycle monitor may have an offset. A duty cycle code for the duty cycle adjuster may be set to an intermediate value of a duty cycle monitor offset. The duty cycle monitor offset may be determined by identifying duty cycle codes for an upper and for a lower boundary of the duty cycle monitor offset.
Claims20
A method, comprising:
- adjusting a value of a duty cycle adjuster circuit setting until an upper boundary and a lower boundary of an duty cycle monitor offset is identified;
- and
- setting the duty cycle adjuster circuit setting to an intermediate circuit setting in the duty cycle monitor offset.
An apparatus, comprising:
- a memory;
- a command/address bus;
- a data bus;
- clock bus;
- and
- a memory controller coupled to the memory through the command/address bus, the data bus, and the clock bus, the memory controller configured to:
- adjust a value of a duty cycle adjuster circuit setting until an upper boundary and a lower boundary of an duty cycle monitor offset is identified;
- and
- set the duty cycle adjuster circuit setting to an intermediate circuit setting in the duty cycle monitor offset.
