In addition to ultra-high-speed data processing, modern IoT devices require long-lasting batteries. To achieve this, onboard RAM needs to operate efficiently by using the lowest possible power settings. Low power synchronous dynamic RAM (Low power SDRAM) integrates energy-saving technology that allows IoT devices to operate at optimal levels for longer periods.

How Does Low Power SDRAM Work?

A low power SDRAM operates similarly to a conventional synchronous dynamic RAM unit. Data transference is achieved via a finite state machine that channels clock signals. Just like with regular SDRAM, low power SDRAM permits command channeling where new commands are received while ongoing tasks are being processed. Low power SDRAM also integrates various features designed to minimize power consumption in both idle and active periods. 

Distinctive Features of Winbond Low Power SDRAM

Winbond’s Low power SDR SDRAM product family is designed with specific features to reduce power consumption, including Partial Array Self Refresh (PASR), Auto Temperature Compensated Self Refresh (ATCSR), Power-down mode, Deep power-down mode, and Programmable output buffer driving strength.

Why Choose Low Power SDRAM?

Mobile phones and other IoT devices spend a reasonable amount of time in idle mode when waiting to be used for the various applications they perform. While in this quiescent state, they continue to utilize power.

Integrating a smart low power RAM allows mobile phones to adapt their energy usage according to the level of data processing required. This allows them to significantly extend the battery life and boost overall energy efficiency.
