The memory market is feeling the effects of a fall in PC shipments with the subsequent stabilization of DRAM prices, which industry observers say will delay the wide adoption of the upcoming DRAM called DDR4.
The latest PCs and servers come with DDR3 SDRAM, and mobile devices have just started getting a type of low-power memory called LPDDR3 (low-power DDR3). DDR4 is the successor to DDR3, and consumes 20 percent to 40 percent less power while offering double the throughput of its predecessor.
But with memory prices stabilizing after years of double-digit drops, analysts said that DDR3 DRAM will likely have a longer-than-expected life, which could delay the wide adoption of DDR4 in computers. DRAM prices have stabilized as demand for DDR3 has exceeded supply, and the number of memory makers has also dwindled. Samsung, SK Hynix, and Micron dominate the DRAM market, while other memory makers have either been acquired or are focusing on the more profitable NAND flash business.
The volume shipments of PCs and servers are not enough to justify an early switch to DDR4, analysts said. Also, a lot of focus is now on the fast-growing tablet and smartphone markets, so manufacturers are shifting capacity to LPDDR3 and other forms of mobile memory and storage.
