PSRAM (Pseudostatic DRAM)

HyperBus™ is a low signal count, DDR interface, that achieves high-speed read and write throughput. It 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.

HyperBus™ can also support external NOR flash and RAM on the same bus, and works with any microcontroller with a HyperBus™ compatible peripheral interface. This only require 13-pins for data transactions (12-pin HyperBus™ + 1 additional chip select for the second memory device).

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.
