In flash memory, when the time of data storage reaches a certain value, it will be wrong because of the TAT effect. However, the Read Scrub technology of SSDs will reduce the error that ECC can't correct, so as to solve the problem of data retention. And there are also some data integrity techniques to ensure data integrity.

Knowledge of NAND flash

This article will clarify the misconceptions about NAND flash memory. SSD may perform bad because poor quality of controller. SATA SSDs are still in high demand although PCIe dominates many consumer markets. As the function of the average erasing storage block technology being used, flash memory will break sooner or later. High-order custom managed NAND solutions can be easily built. Solutions are...

New chip architecture opens up the era of security operation

At this year's Hot Chips conference, industry experts called for a new generation of security-designed computer architecture to avoid the recurrence of Spectre/Meltdown security breaches. Surprisingly, to create safer products, Microsoft described the Pluton security module, while Google introduced Titan, which is expected that the two companies could merge into a standard one day.

What is NVMe?

Source: local   Editor: Alex   Update Time :2018-12-11
NVMe, short for Non-Volatile Memory Express, is a protocol that makes solid-state drives (SSDs) run faster, and is gaining popularity among enterprise users. It makes full use of the low latency and parallelism of PCI-E channel, as well as the parallelism of modern processors, platforms and applications. With controllable storage costs, NVMe can greatly improve the read-write performance of SSDs,...

The physical structure of flash memory

Flash is a kind of nonvolatile memory, whose basic storage cell is an NMOS-like bilayer floating gate MOS transistor. The write operation or erase operation depend on electrons enter or escape from the foating gate. According the size of data stored in a storage cell, flash is divided into SLC , MLC and TLC.

How many process will be from sand to Wafer ?

Many people may wonder how the sand becomes wafers. In fact, the sand is purified into polycrystalline silicon, and then polycrystalline silicon is used as raw material to make monocrystalline silicon. Silicon ingots, after being cut, rolled, sliced, chamfered, polished, laser engraved and packaged, become the basic raw material for integrated circuit factories—wafers.

The difference between UFS memory card and traditional Micro SD card

Source: local   Editor: Alex   Update Time :2018-12-06
Recently, Samsung has released a new UFS memory card with a capacity of up to 256GB, which completely crushes the existing Micro SD (TF card) flash card at the reading and writing speed. Although there is no obvious difference in appearance between them, UFS card with higher cost has a larger capacity than TF card. The actual performance of UFS memory card is very worthy of our expectation.
