Low Power DDR2 SDRAM

The use of double data rate synchronous dynamic random-access memory (DDR SDRAM) in modern IoT devices has significantly improved computer data processing. While DDRs allow faster data transmission than single rate memories, the improved performance often translates to greater power consumption. Low power DDR2 memories are designed to operate on low power without compromising performance.

How Does a Low Power DDR2 SDRAM Function?

A Low power DDR2 is essentially an optimized double data rate SDRAM and operates similarly. Data transfer is done on both the rising and falling edges of the clock signal (double pumping). As with conventional DDR memories, low-power DDR2 SDRAM achieves greater bandwidths without any change in clock frequency.

Distinctive Features of Low Power SDRAM

Low power DDR2 SDRAM is optimized for mobile applications in two areas:

• Active power usage
• Standby power mode

Low power DDR2 RAM variants consume less power when in active use than standard DDR2s. When mobile devices are left to idle, low power DDR SDRAM activates various power-saving features to improve battery life.

Power Saving Features of Winbond Low Power DDR2 SDRAM

Winbond’s Low Power DDR2 (LPDDR2) 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.

LPDDR vs. LPDDR2

While both LPDDR and LPDDR2 memories are optimized for power-saving mobile applications, LPDDR2 has significant improvements over LPDDR. LPDDR2 achieves faster rates of data transfer and also has larger density options.
