Soaring memory prices led by DDR4 and DDR5 are spooking users, which are buying as soon as they receive a quote, hoarding what they can get and accepting that they may not get what they want. According to Yicai Global, the financial news arm of Shanghai Media Group, in August 8GB DDR4 modules were selling below $12:60, but in September ...

JEDEC has announced an update of the DDR5 Serial Presence Detect (SPD) Contents standard, JESD400-5D. The SPD data is used by a system’s BIOS to properly initialise and optimise memory channels. The annual release – this is version 1.4 – adds support for memory modules executing up to DDR5-9200 speeds. There are also codes for the new Small Outline Compression ...

Teledyne e2v has introduced engineering models of its forthcoming 16Gbyte radiation-tolerant DDR4 memory. “With the release of our engineering model, system architects can begin early validation, preparing for a transition to flight-qualified versions,” said Teledyne marketing manager Thomas Guillemain. The memory measures 15 x 20 x 1.92mm and it pad-compatible with the company’s earlier 4 and 8Gbyte DDR4 ICs which ...

By the end of 2024, the DRAM industry is expected to have allocated approximately 250K/m (14%) of total capacity to producing HBM TSV, with an estimated annual supply bit growth of around 260%, says TrendForce svp Avril Wu. HBM’s revenue share within the DRAM industry—around 8.4% in 2023—is projected to increase to 20.1% by the end of 2024. The die ...

JEDEC has published a new JESD318 Compression Attached Memory Module (CAMM2) Common Standard, which defines the electrical and mechanical requirements for Compression-Attached Memory Modules. It covers both Double Data Rate, Synchronous DRAM Compression-Attached Memory Modules (DDR5 SDRAM CAMM2s) and Low Power Double Data Rate, Synchronous DRAM Compression-Attached Memory Modules (LPDDR5/5X SDRAM CAMM2s). The standards body highlights that DDR5 and LPDDR5/5X ...

Teledyne e2v is shipping 4byte radiation-tolerant space-grade DDR4 memory. The device, called DDR4T04G72, is a 15 x 20 x 1.92mm multi-chip module that can operate at 2.4Gtransfer/s. Its bus assigns 64bits to data and an additional 8bits to error correction. The company sees it being used with its own Qormino processors, and the memories are compatible with “the vast majority of processors, ...

Alliance Memory has introduced fast 128 and 256Mb CMOS synchronous DRAMs in 54ball TFBGA packages. Sized 8x8x1.2mm, the memories are 8Mx16 and 16Mx16 with...
