IoT is expected to further push high end server, router, intelligent TV, smart phone and PC demand to cater to higher numbers of online devices. Devices with high end graphics and smart interfaces are going to be the key to success. This requires high end performance and computational power, which has been the forte of traditional DRAM (DDR/LPDDR) technology.
The traditional DRAMs (DDR2/3/4 and LPDRR2/3/4) are available as discrete components in various densities ranging from 32 MB to 2 GB, whereas commercial DIMMs (multiple DRAMs put together) can accommodate storage up to 128 GB. 3DS technology is another step towards not only increasing memory storage beyond the maximum available DIMMs but also simultaneously decreasing power consumption. There is a margin of decrease in power consumption because there are no more physically connected DRAMs (to create DIMMs) on board, but rather a single chip wherein multiple layers are stacked during chip manufacturing.
Low power DDR (LPDDR2/3/4) will continue to dominate the mobile and hand held device market. LPDDR4 draws 1.2V of power compared to 1.5V required by LPDDR3, resulting in more than a 20% drop in power requirements, together with high speeds of 3200 MHz. LPDDR3’s performance is more than capable of serving most IoT applications, which require low power and higher performance.
Synopsys has been the market leader in the traditional DRAM controller and PHY market for years. The DesignWare® Enhanced Universal DDR Memory and Protocol Controller IP feature a DFI-compliant interface, low latency and low gate count while offering high bandwidth. Along with providing DDR controller and PHY, Synopsys also provides Verification IP for DDR and other memory protocols, which can be used to accelerate IP verification.
