SSD core components master chip detailed explanation

Solid state hard disk (SSD) is an electronic integrated board composed of main control chip, flash memory granule and buffer unit. In these three pieces, the high cost of procurement is undoubtedly flash memory particles, and the technical content and core technology is the main control of new products.

SSD master is essentially a processor, mainly based on ARM architecture, which is similar to mobile phone processor. Some SSD manufacturers use RISC architecture to make them have CPU level computing power.

Different architectures, the number of cores / transistors and the frequency are related to the performance of the main controller. It can be said that the quality of a master chip directly determines the actual experience and service life of SSD.

So what are the dominant brands in the market?

At present, the main brands in the mainstream market are Samsung, Huirong, qunlian and Marvell.

Samsung master:

Samsung Electronics, as one of the few semiconductor enterprises in the world, has a complete ecological chain of semiconductor design, processing, manufacturing, production and sales. It occupies a place in the field of master chip of solid-state drive, and creatively develops a series of master chips based on Samsung's own firmware.

Samsung's main control is mainly corresponding to Samsung's own products, and the products still have quite brilliant performance in cache technology, signal processing, etc.

Huirong is in charge of:

The main advantage of Huirong technology in SSD master chip is that it can provide a complete set of SSD solutions from master chip to firmware solution, then to circuit board design, flash particle matching and so on. It can also provide customized services according to the individual needs of the purchasers.

Jingzhe's one-stop service, for some enterprises in the SSD industry, can greatly solve their practical problems, and can quickly improve production capacity and enter the market.

Recently, Huirong technology released a new SSD controller solution. It includes ultra high speed sm2262 for client and enterprise applications, sm2263 for mainstream applications, and sm2263xt DRAM free controller supporting BGA package.

Group connection master:

Qunlian electronics has been established for 17 years with a market value of over 10 billion. It has strong technical strength. In addition to CPU core, all modules in SSD main control chip are independently researched and developed by qunlian, with a full set of IP technology.

It is reported that qunlian will purchase $800 million worth of flash memory particles every year and provide them to customers after making an integrated solution with the master controller. Moreover, qunlian has all the technologies and products of SSD application industry and provided 20 million flash memory to the medical field last year.

The chips of group master control, from USB flash disk master control design to SSD master control, are famous for their cost performance. Especially in the early stage of SSD development, group master control occupied most of the brand market with its super cost performance.

Marvell master:

As a technology-based Fabless Semiconductor R & D company, Marvell has made considerable achievements in chip design, mass storage solutions, mobile and wireless technology, network, consumer products, etc.

Specifically, in the field of storage, Marvell is the market leader of data storage solutions, involving consumer market, mobile product market, desktop product market, enterprise market and many other fields.
