Tech Overhaul: An Ode to Faster Memories


If you want to know a person’s ‘true’ side, give him or her a ‘slow’ computing device! This might sound like a joke but most people assume a ‘demonic’ avatar when they aren’t able to view videos, emails or play games on their hand-held gadgets such as phones or tablets at the desired speed. You could find them clenching their fists (this includes me)…

Arastu Systems’ DFI 3.1 compatible and validated DDR4 Controller Core for increased system performance and reliability


June 7th, 2016, San Jose, CA – Arastu Systems, a company that specializes in developing IPs in the Memory and Networking area today announced its DDR4 DRAM Memory Controller considering the need for higher performing, higher densities memories in applications pertaining to Data Center and Enterprise market. The IP is compliant to popular industry standards as well customized for specific customer’s needs.

The controller is designed as per JEDEC standard JESD79-4A and works seamlessly with our partner’s DFI PHY or DFI 3.1 compatible PHY from any other vendor. The design IP is developed using standard synthesizable RTL and supports data rates up to 3200 MT/s. Thereby, increasing the DRAM performance up to 50% over the predecessors. Additionally, it also supports multiple power saving modes that includes Low Power Auto Self Refresh (LPASR) which helps saving power close to 35% from previous versions.

The design IP supports features such as CRC computation across the data bus for error detection, parity generation for command/address bus to verify the integrity. It provides seamless error recovery which reduces the complexity of error recovery process in contrast to earlier DDR versions. It also supports Error Correction Code (ECC) which helps in correcting single bit error, and is imperative in applications such as spacecraft communication where reliability is a key factor.

”Technologies such as Cloud Computing, Virtualization and High-Performance Computing  requires high-capacity and highly-reliable memory subsystems” said Umesh Patel, CEO and Founder, Arastu Systems. “We are assisting our customers with our robust, self-contained and highly modular DDR4 and the upcoming DDR3/4 combo solution”.

Arastu Systems announces DFI 4.0 compatible and validated LPDDR4 DRAM Memory Controller


April 7th, 2016, San Jose, CA – Arastu Systems, a company that specializes in developing products in the Memory and Networking area, today announced its LPDDR4 DRAM Memory Controller to cater the increasing demand for high performance and low power memories. The design IP supports popular industry standard AHB/AXI, but gives customers the flexibility to customize the design as per their needs.

The controller is designed as per the JEDEC standard JESD209-4A and works seamlessly with partner’s DFI PHY or DFI 4.0 compatible PHY from other vendors. The IP is developed using verilog and supports speeds up to 3200 MTps (MegaTransfers per second) for applications where faster response rates and  faster processors are mandatory, in order to achieve optimized end user experience.

The LPDDR4 IP solution also saves power by supporting multiple power saving modes such as Self Refresh Power Down, Deep Power Down, thereby extending the battery life of consumer gadgets. It supports multiple channels and gives privilege to the user to configure and manage each channel independently and also maximizes DRAM bus utilization using Look-Ahead command processing and Bank Management.

The LPDDR4 DRAM controller facilitates secure access to memory thereby assuring protected data transfer mainly for applications such as Advanced Driver Assistance Systems and Infotainment in the automotive industry, where security is the key concern. The core also supports DRAM testing, thereby increasing the system’s reliability.

“DRAM business has always been challenging, the memory requirement for each system is  different and to add to that faster computing solution demand faster and better memories” said Umesh Patel, Founder and CEO, Arastu Systems. “Our highly configurable and easily customizable DRAM solution amalgamated with our focused approach and clear vision is helping us cater the market needs.”
