UNMATCHED CLOCK FOR COMMAND-ADDRESS AND DATA - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240112720 titled 'UNMATCHED CLOCK FOR COMMAND-ADDRESS AND DATA
Simplified Explanation
The memory system described in the patent application includes a physical layer (PHY) on an integrated circuit that connects to a memory via conductive traces on a substrate. The PHY comprises a reference clock generation circuit, a first group of driver circuits for CA signals, and a second group of driver circuits for DQ signals. The DQ signal traces are longer than the reference clock signal traces to reduce insertion delay when coupling the clock signal to latch incoming DQ signals.
- Explanation of the patent:
* Memory system with a PHY on an integrated circuit * PHY includes reference clock generation circuit, driver circuits for CA and DQ signals * DQ signal traces are longer than clock signal traces to reduce insertion delay
- Potential Applications:**
The technology could be applied in various memory systems, such as DRAM, SRAM, or flash memory, to improve signal integrity and reduce delays in data transmission.
- Problems Solved:**
1. Reduced insertion delay when coupling reference clock signal to latch incoming DQ signals 2. Improved signal integrity in memory systems
- Benefits:**
1. Enhanced performance and reliability of memory systems 2. Reduced data transmission delays 3. Improved overall system efficiency
- Potential Commercial Applications:**
Optimizing memory systems for faster data processing Improving signal integrity in high-speed memory applications
- Possible Prior Art:**
Prior art may include patents related to memory system design, signal integrity optimization, and clock signal distribution in integrated circuits.
- Unanswered Questions:**
- 1. How does the longer DQ signal traces specifically reduce insertion delay in the memory system?**
The abstract mentions that the DQ signal traces are longer than the clock signal traces to reduce insertion delay, but it does not provide a detailed explanation of the mechanism behind this reduction.
- 2. Are there any potential drawbacks or limitations to extending the length of the DQ signal traces in the memory system?**
While the longer DQ signal traces are intended to reduce insertion delay, it is important to consider if there are any trade-offs or challenges associated with this design choice, such as increased signal degradation or complexity in routing the traces.
Original Abstract Submitted
a memory system includes a phy embodied on an integrated circuit, the phy coupling to a memory over conductive traces on a substrate. the phy includes a reference clock generation circuit providing a reference clock signal to the memory, a first group of driver circuits providing ca signals to the memory, and a second group of driver circuits providing dq signals to the memory. a plurality of the conductive traces which carry the dq signals are constructed with a length longer than that of conductive traces carrying the reference clock signal in order to reduce an effective insertion delay associated with coupling the reference clock signal to latch respective incoming dq signals.
