An independent counting clock decouples ECS from refresh commands, helping semiconductor memory finish error scrub on time with lower power.
Interchanging latch clock signals in one latch group keeps divided clocks at 50% duty even for odd division ratios.
A multiply-then-divide converter creates balanced differential outputs from a single-ended signal to improve TDC linearity and zero-crossing stability.
Interchanged latch clock signals let a cyclic clock divider keep a 50% duty ratio even when the division number is odd.
During overcurrent events, the circuit switches among divided clock frequencies to avoid shutdown, protect the chip, and preserve computing power.
Internal clock leveling uses feedback between system and data clocks to compensate signal skew in daisy-chained semiconductor memories.
Clock leveling feedback aligns system and data clocks in serial semiconductor memories to compensate skew and stabilize data transfer.
Programmable duty cycle control in a synchronous clock divider compensates aging and chip variation to keep divided clocks stable.
A counter and phase-aligned flip-flops divide multi-phase clock inputs while preserving phase offsets and reducing clock generator area.
