SK Hynix already manufactures 238-layer NAND Flash memory

The development of NAND Flash memory with a greater number of layers represents important work because, in the end, this is the key to achieving higher storage density. If we look at the past we will realize that in this sense we have experienced an important evolution, and we will also see that it has occurred in a very short time.

For example, three years ago we were already talking about 64-layer NAND Flash memory chips, and the 128-layer setups started to get loud soon after. Now we see ourselves at values ​​that practically double those figures, and it is expected that this trend will continue for the next few years, since it is essential for the development of new storage solutions, I am not referring only to high-performance SSDs, but in general to any drive that uses NAND Flash memory chips.

According to SK Hynix its 238-layer NAND Flash memory chip it is the smallest of its kindsomething that will facilitate its integration in devices and equipment where space is a very limited resource, and is also capable of reaching a 50% improvement in transfer speeds of data versus the previous generation of chips. Impressed? Well wait, there is still more, and it is that efficiency has also been improved, thanks to a consumption reduction of 21% (in read operations).

Although SK Hynix already has units produced of this chip, it is important to note that it will not come into mass production phase until the first half of 2023which means that its integration into commercial products, both general consumer devices and storage units, will not start until the second half of 2023. With this in mind, I think it is likely that we will not see the first products based on such technology until end of 2023.

SK Hynix is ​​one of the largest manufacturers of NAND Flash memory, and with this move it only strengthens its position in a very competitive market, where today represents 18% of the total market share. Samsung overtakes it with 35.3% total market share, and is also slightly behind Kioxia, who maintains 18.9% market share.
