Understanding the memory-storage pyramid

Loren Shalinsky, a Strategic Development Director at Rambus, recently penned a detailed article for Semiconductor Engineering that explores the memory-storage hierarchy. As he puts it, the hierarchy, or pyramid, is a particularly succinct method of understanding computer systems and the dizzying array of memory options available to the system designer. “Many different parameters characterize the […]

Navigating the DDR4 adoption road map

The projected adoption rate of DDR4 as the dominant industry memory standard was a major topic of discussion at Intel’s Developer Forum earlier this month, with the company confirming DDR4-2400 support for its upcoming Xeon E5-2600 V4 CPUs. “The current mainstream platform Skylake also provides DDR4 support of up to 2133 MHz,” Dennis Bode of […]

Future challenges for DDR4 and beyond

Ely Tsern, VP and chief technologist for the Rambus Memory and Interfaces division, has identified five key trends driving future server memory. These include Big Data, additional cores per CPU, a DRAM scaling slowdown, the emergence of storage class memory and the expectation that DDR4 will ultimately reach its speed limit. “Rambus is working with […]

Use Cases: Personalization

Related to the inherent complexities and costs associated with building a brand new chip, fabless chip manufacturers are under constant pressure to improve operating efficiencies while, at the same time, satisfying OEM customer requirements. As such, large OEM customers requesting personalization, customer specific data preparation and feature customization of standard parts challenge the chipmakers ability […]

Use Cases: Secure Key Provisioning

With mobile devices housing more and more sensitive data that is utilized in a wide variety of applications, chip and device companies must meet the complex security requirements for each potential use case or capability. Most security measures require the injection of secret identity data and cryptographic keys. Currently, cryptographic keys are provisioned in the […]

Use Cases: Debug Access Control

When chips are shipped into the field, it is required that test features, needed to test the chip during manufacturing, must be securely disabled (see Figure 1 below). If left enabled in the field, these test and debug ports could provide a back door into the device that could be used maliciously to read sensitive […]

TECHnalysis Research talks Rambus server memory chipsets

Bob O’Donnel of TECHnalysis Research recently published a white paper describing the critical role memory server chipsets play in facilitating high-speed DDR4 designs. “With the introduction
