The proliferation of the Internet of Things (IoT) and mobile devices in the consumer, industrial, and medical spaces is continuing to drive the development of various memory technologies. Mobile DRAM (dynamic random access memory) is one of the promising memory technologies that has been emerging and evolving to meet the requirements of the IoT devices that are required to offer more functionality in less space while using less power.
New SDRAM devices in a wide range of densities and package options
To meet the high demand for low-power memory technologies for IoT and mobile devices, Alliance Memory has recently updated its SDRAM (synchronous DRAM) portfolio to include a wide range of densities and package options. These components claim to combine low power consumption with power-saving features to extend battery life in mobile devices.
- Featuring power consumption of 1.8V, the company’s LPSDR SDRAMs are available in densities of 128Mb, 256Mb, and 512Mb in 54-ball and 90-ball FBGA packages.
- LPDDR devices feature power consumption from 1.7V to 1.95V and densities of 256Mb, 512Mb, 1Gb, and 2Gb in the 60-ball and 90-ball FBGA packages.
- Said to enable ultra-slim designs, LPDDR2 SDRAMs offer power consumption of 1.2V/1.8V and densities of 1Gb, 2Gb, and 4Gb in the 134-ball FBGA package.
The company noted that its low-power SDRAMs offer a variety of power-saving features, including auto temperature-compensated self-refresh (TCSR) to minimize power consumption at lower ambient temperatures. In addition, their partial-array self-refresh (PASR) feature reduces power by only refreshing critical data, while a deep power down (DPD) mode provides an ultra-low power state when data retention isn’t required.
“With the Internet of Things and proliferation of mobile devices in the consumer, industrial, and medical spaces, we’ve committed ourselves over the past few years to solidifying our offering of low-power ICs,” said David Bagby, Alliance Memory president and CEO.“ It began with the introduction of our LPSDR SDRAMs in 2014, followed by our LPDDR devices in 2016, and LPDDR2 SDRAMs in 2017. Now we offer a complete low-power portfolio in a wide range of densities and package options to meet the high demand for these parts.”
