Can China make memory modules? Can China make memory particles?

There is no domestic technology, some brands are foreign brands, foreign technology, and OEM factories are available in China.

A memory module is a part of a computer that can be addressed by the CPU and can be read and written. Memory modules used to be an extension of the main memory in the history of personal computers. With the continuous update of computer software and hardware technology, memory modules have become the whole of read and write memory.

When we talk about the size of a computer's memory (RAM), we refer to the total capacity of the memory module. Memory modules are an essential part of a computer, and the CPU can address the memory through the data bus. Historically, computer motherboards had main memory, and memory modules were extensions of the main memory.

Later computers will not have main memory on the motherboard, and the CPU will rely entirely on memory modules.

All content on external memory must pass through memory in order to function. Memory is divided into DRAM and ROM, the former is also called dynamic random access memory, one of its main features is that data will be lost after power failure, we usually refer to this kind of memory; The latter is also called read-only memory, we usually start the BIOS program stored in the ROM on the motherboard first, and then it calls the Windows in the hard disk, one of the main features of the ROM is that the data will not be lost after power failure.

This 256MB Kylun memory runs at DDR400, using single-sided 8 x 32M particle specifications, in order to ensure the stable operation of the memory, Kylun sets the memory CL delay time to, and also sets the SPD value, which is the motherboard's self-test reading when booting, which helps to improve computing performance. Domestically produced in Shandong.

Most of the world's products are made in Taiwan.

Isn't that made in China?

Can be manufactured. In fact, China's independent 3D NAND flash memory particles have long been ready to launch, and will be launched at the end of 2017 at the earliest, and it is a 32-layer stack, and the starting point is not low.

Overview

The crazy rise of memory modules and SSDs is "due to" the lack of raw material production capacity, that is, the insufficient production capacity of NAND flash memory particles, which has caused the crazy price increase of memory modules and SSDs. You must know that in the field of flash memory, mastering flash memory particles can almost be said to control the flash memory market (including memory modules, SSDs, memory cards, etc.). At present, there are countless manufacturers engaged in the manufacture of NAND flash memory particles in the world, but there are only six dominant ones, they are Samsung (Samsung), Toshiba (Toshiba), Intel (Intel), Hynix (SKHYNIX), Micron (Micron), SanDisk (Sandisk), these six manufacturers engaged in the manufacture of NAND flash memory particles almost monopolize most of the global flash memory market share.

China's local flash memory particle manufacturers, such as Unisplendour Technology and Xinxin Technology, did not make the list.

In fact, China's independent 3D NAND flash memory particles have long been ready to launch, and will be launched at the end of 2017 at the earliest, and it is a 32-layer stack, and the starting point is not low. You know, the above six manufacturers have been developing for many years, and the first generation of 3D flash memory launched is only a 24-layer stack, as far as the current flash memory market is concerned. The 32-layer stack is fairly mainstream.

Although the 48-layer or even 64-layer stacked 3D flash memory of these world's first-tier manufacturers may be available by the end of the year, the launch of 3D NAND flash memory chips with 32-layer stacks by Chinese manufacturers is a big step. There is a gap with the international first-line manufacturers, but the gap should be narrowed a lot, and there is still a chance for domestic 3D flash memory to catch up.

When the domestic 3D NAND flash memory particles mature, it is bound to stir up the entire flash memory market. It is believed that the phenomenon of the crazy rise of flash memory products will be suppressed. All of this will benefit consumers.

Consumers like this writer are desperate for such "spoilers" to emerge sooner rather than later.

Not before, but this year domestic manufacturers have received large investment and are ready to produce completely localized large memory particles. With the support of Da**, SMIC and Huali Micro, the two largest wafer foundries in China, began to expand their production capacity on a large scale. On October 13, 2016, SMIC invested nearly 100 billion yuan to start a new 12-inch production line in Shanghai, with a process of 14nm and below, with a monthly production capacity of 70,000 pieces. In addition, SMIC has invested in the construction of a 12-inch production line with a monthly production capacity of 40,000 pieces in Shenzhen, and invested in expanding the production capacity of the original Tianjin 8-inch plant in Tianjin, from 10,000 pieces per month to 150,000 pieces per month.

Huali Micro announced the launch of the second phase of the 12-inch high-tech grade production line construction project, with a total investment of 38.7 billion yuan and a planned monthly production capacity of 40,000 pieces.

There is no such technology yet.

I believe there will be in the future.

Although there is still a gap in technology, the development of independent processors and memory is already trying to catch up, which has caused panic among industry giants.

A big breakthrough in domestic independent memory: Competitors are not calm.

Recently, Hefei Changxin Co., Ltd. invested 7.2 billion US dollars to build a 12-inch DRAM factory has started, its monthly production capacity is up to 10,000 wafers, such a capacity performance is similar to SK Hynix's current performance, and there is still a gap compared with Unisplendour's 12-inch wafer factory in Wuhan, the latter's production capacity is expected to be 200,000 pieces per month.

No one knows exactly when this happens.
