Flash Storage

Flash memory is ubiquitous in small computing devices and becoming more common for
larger applications. The size and complexity of flash-based systems varies for storage in wearable computing devices, embedded
systems, smart phones, portable USB drivers and more, all the way up to enterprise-class all-flash arrays

Flash Memory Solutions

Mega Electronics has total solutions such as package design and package assembly. Mega has the
technology to manufacture 3D TLC NAND or QLC NAND on a local assembly line using multi-stack
technology and provides high-performance Know Good Die (KGD) products that require memory or
system-in-package (SiP) for quality control.

Thermal Considerations

One of the important concern with SSDs is there greater susceptibility to temperature throttling . Typical SSDs
in 2.5” form factors leverage thermal pads that wick heat away to be extender of the case. This technique
keeps temperature within an acceptable range in high-heat system environments, but M.2 and mSATA SSDs
can overheat under heavy load , which results in throttling in the best case and failure in the worst case.
We do analysis and design a thermal solution in the early stage of SSD development that meets system
requirements for various applications to optimize thermal load throughout the data storage system.

EMI Considerations

Noise generated by the high-speed file transferring rate of an SSD device will interfere with
wireless systems. Moreover, noise generated by SSD controller also seriously interferes with 3G,
LTE, and Bluetooth, WLAN. If the noise budget of SSD is not controlled at the R&D stage cautiously,
the EMI issues will definitely arise and have a significant impact on computer systems and other
interface. MEGA Electronics has a solution to the EMI in SSD Module

Endurance Considerations

Due to the characteristics of NAND flash, SSDs have a finite lifetime dictated by the number of write
operations known as program/erase (P/E) cycles NAND flash can endure. SSDs come in a variety of endurance
points matched against their intended work pattern. Techniques such as wear leveling and over-provisioning
are common in improving SSD endurance. Wear leveling ensures even wear of memory blocks across the flash
device by evenly distributing all write operations, thus resulting in increased endurance
