Yesterday was Memcon time again. Memcon is the event that Denali started as a one-day conference in Silicon Valley that is all about memory. After Cadence acquired Denali, Cadence now hosts the event.
Along with Memcon, we typically see at least one related press release. The one from Cadence this year really caught my eye. Yesterday, Cadence issued a press release that was titled “Cadence Announces Industry’s First Multi-Protocol DDR4 and LPDDR4 IP Solution”. http://www.cadence.com/cadence/newsroom/press_releases/Pages/pr.aspx?xml=101015_ddr4&CMP=home The release states “Extends memory leadership from LPDDR3/DDR4/3 to include LPDDR4 with performance up to 3200Mbps.”
Are they really “First” or “Leading”?
Synopsys issued an April 23, 2014 press release announcing our LPDDR4 IP Solution. That press release stated “Supports LPDDR4 up to 3200 Mbps with low power consumption. Backward compatibility with LPDDR3 and DDR3/4 SDRAMs simplifies design transition from one SDRAM standard to the next”. http://news.synopsys.com/2014-04-23-Synopsys-Announces-Industrys-First-Complete-LPDDR4-IP-Solution-for-High-Performance-Low-Power-Mobile-SoC-Designs
The products appear similar, but one was announced 6 months before the other. You decide, is the Cadence announcement a truthful press release?
