LPDDR5X memory in smartphones – features and benefits

What are the characteristics of LPDDR5X memory, and what are its main advantages?

The updated LPDDR5X memory standard significantly outperforms previous versions in both performance and power savings. Here are the main features and benefits that bring LPDDR5X memory to a new level of development.

One of the main characteristics of LPDDR5X memory is a significant increase in performance. First of all, this improvement will favorably affect the work of demanding applications, for example, programs involving artificial intelligence and applications for work and graphics processing. In addition, increased performance will allow you to increase the autonomy of smartphones with a 5G network. Overall, performance has increased by more than 33% over the previous standard.

Other important benefits were an increase in the maximum data transfer rate to 8533 Mbps, as well as a reduction in power consumption. Thus, the memory can meet the market demand for Ultra HD multimedia content. In addition, increased throughput will optimize the process of powerful calculations in the field of machine learning.

Compared to LPDDR5 memory , LPDDR5X has faster speed but uses the same voltage. In this case, it is possible to reduce the data transfer rate by reducing the voltage.

Other equally significant changes and innovations in LPDDR5X memory include the following features:

• Preselect function. The LPDDR5X offers a unique feature whereby the transmitted signal is pre-allocated to compensate for any transmission loss that has occurred.
• To reduce errors during transmission, high-speed data transmission uses a pin-alignment technique to maintain signal integrity.

Comparison of LPDDR5X memory with previous memory formats

For a more visual comparison of LPDDR5X memory with past memory formats, it is necessary to consider all the significant characteristics, as well as how they have changed over time:

Maximum data transfer rate

Currently, the LPDDR5X memory standard has the highest bandwidth:

• LPDDR5X – 7466 ⁓ 8533 Mbps.
• LPDDR5 – 5500 ⁓ 6400 Mbps.
• LPDDR4 (X) – 3200 ⁓ 4266 Mbps.
• LPDDR3 – 1600 ⁓ 1866 Mbps.
• LPDDR2 – 800 ⁓ 1066 Mbps.
• LPDDR – 333 ⁓ 400 Mbps.

Max Voltage

LPDDR5X and LPDDR5 memory operate in the same voltage ranges:

1. LPDDR5X and LPDDR5 – 1.05V / 0.5V.
2. LPDDR4 (X) – 1.1V / 1.1V (0.6V).
3. LPDDR3 – 1.2V/1.2V.
4. LPDDR2 – 1.2V/1.2V.
5. LPDDR – 1.2V / 1.2V.

Single chip capacity

As in the previous paragraph, the characteristics of the LPDDR5X and LPDDR5 memory remained the same:

• LPDDR5X and LPDDR5 – 8 Gb ⁓ 24 Gb.
• LPDDR4 (X) – 4 Gb ⁓ 24 Gb.
• LPDDR3 – 1 Gb ⁓ 8 Gb.
• LPDDR2 – 256 Mbps ⁓ 4 Gbps.
• LPDDR – 128 Mbps ⁓ 2 Gbps.

Thus, LPDDR5X memory outperforms its predecessors not only in advanced features, but also in maximum data transfer speed. The increase in speed at the same voltage makes the LPDDR5X more advanced in terms of power saving.
