PSRAM (Pseudostatic DRAM)

HYPERRAM™ devices are able to achieve high bandwidth compared to traditional parallel expansion memories via the HyperBus Interface. The HyperBus interface utilizes a high-speed 8-bit DDR interface for both address and data along with a differential clock, a read/write latch signal, and a chip select. Both HyperBus and the Octal xSPI interfaces are JEDEC compliant.

HyperBus can also support external NOR flash and RAM on the same bus, and works with any microcontroller with a HyperBus compatible peripheral interface. Visit our HyperBus memories page to know more about HyperFlash memory and HyperRAM + HyperFlash Multi-chip package (MCP) solutions.
To understand how the HyperRAM™ enables a low-pin expansion memory solution, read this whitepaper.

HYPERRAM™ products achieve far higher throughput per pin compared to competing technologies such as traditional pSRAMs and SDR DRAMs which are based on a parallel interface. The in-built self-refresh circuitry and low-power features such as partial array refresh and hybrid sleep enable lower power consumption making HyperRAM apt for power constrained applications such as wearables and IoT devices.
