It is available in both Single-Die-Package (SDP) with a 2Gb density and Dual-Die-Package (DDP) with a 4Gb density. The higher speed of LPDDR4 1CH x16 4267 Mbps offers improved performance over previous DDR4 x16 3200 Mbps devices, which is especially useful for consumer applications. Read ...
Samsung this week announced that it has begun manufacturing its new LPDDR4X memory chips using its second-generation 10 nm-class fabrication process (which is traditionally called 1y nm). The new technology enables the company to slightly cut down power consumption of the new memory devices as...
TSMC, with $69 billion in sales last year, dwarfs IFS, which saw 2023 revenue more than double to $952 million. Some hesitation experienced Some AI chip designers are hesitant about using IFS as their chip foundry. “I think they’re getting better,” Keith Witek, the COO of Tenstorrent,...
AMD’s Client unit, which the chipmaker had warned about in October, generated $1.02 billion in revenue. That was down nearly 40% but in excess of the $1.17 billion StreetAccount consensus. Four days after AMD gave preliminary results, technology industry researcher Gartner said third-quarter PC...

which resulted in China’s passenger vehicle market recording its biggest drop since the COVID-19-hit March 2020. The situation improved only after lockdowns were lifted during the latter half of May. The second half of 2022 is expected to deliver better results, but economic downturns, energy...
That investment in Changxin Xinqiao Memory Technologies Inc. was one of the largest investments by the flagship semiconductor fund, better known as Big Fund, after Beijing began a probe into its former heads for corruption about a year ago. ...
Additional layers are required if: • The PCB layout area for the DDR Interface is restricted, which limits the area available to spread out the signals to minimize crosstalk. • Other circuitry must exist in the same area, but on layers isolated from the DDR routing. • Additional ...
