Here are answers to some of the most frequently asked questions. Q: What's new about Denali's synthesizable PHY offerings? A: Denali's has extended our PHY architecture to include timing closure and DFM, along with 4 hour implementation time. Most customers prefer a synthesizable PHY delivery and this technology
19 Sep 2011 To implement DDR4 memory in a system-on-chip, you'll need both memory controller IP and PHY IP. If there's a standard interface between the two, you won't
27 Oct 2008 As one of the DDR PHY Interface (DFI) specification participating members, Denali Software, Inc., has announced the availability of the preliminary version of the DFI specification 2.1.

?Multiple arrays organized into banks. ?Multiple banks per memory device. • DDR1 – 4 banks, 2 bank address (BA) bits. • DDR2 & DDR3– 4 or 8 banks, 2 or 3 bank address (BA) bits. • Can have one active row in each bank at any given time. ?Concurrency. • Can be opening or precharging a row in one bank while
Interoperability between a Memory Controller and a PHY is one such challenge. DFi™ is a standard that ensures the compatibility of DDR MC and DDR PHY at target matched frequencies and frequency ratios. In a frequency ratio system, the MC operates at half rate or quarter rate of the PHY frequency. Hence, the timing
