Drive interfaces require trade-offs

....Disk drives have moved from power-inefficient and high-pin-count parallel interfaces to low-power, high-speed serial connections with low pin counts. The older, high-power interfaces, including PATA, SCSI, and PCI, had multiple-data- pin, wide-cable interfaces. The new interfaces, including SATA, SAS, and PCIe, all have high data rates with only a few active pins, thanks to advancements in the use of serializers/deserializers on the interface (Figure 1).Space and power/thermal issues for capacity and storage limit the client side. As a result, the new serial interfaces feature rotating media as the dominant...

Tablet and smartphone demand drives new trends in mobile memory

... than it was when JEDEC first proposed the standard, according to Wong. As such, a solid-state drive with a low-power SATA (serial-advanced-technology-attachment) interface could be an alternative. “For example, the idle power of the SATA PHY [physical layer] is quite large,” he says. “You could make it ‘low power’ by turning off the PHY when [it is] idle.”Setting the standardsJEDEC, a volunteer organization, sets...

Tracking PLL design through the decades, part 2

... frequency synthesis, several other applications of PLLs have become important. The integration of PLLs forms one of the keys to serial chip-to-chip communication. This type of communication requires a SERDES circuit pair. Serial chip-to-chip communication has many benefits, most notably the reduction in IC area, because the PLL and SERDES are typically smaller than the set of parallel I/Os, and in PCB...

Core-logic chip enhances predecessors' features

... and available in 2.5-in. SATA and mini-SATA form factors. The 34-nm, high-reliability, fast-writing, SLC (single-level-cell), flash-memory-based 311 series is a variant of the earlier-announced 310 mini-SATA and X25-M SATA product lines. The 20-Gbyte 311 series drives sell for $110 (1000).Intel...

Solid-state drives: lower SATA speeds but more advanced lithographies

...-disk drive. When using a 3-Gbps SATA bus, which has an installed base of more than 1 billion units, the 320 series devices outperform the X18-M, the X25-M, the mini-SATA-derived 310 series, and the Marvell-powered 510 series.The 320 series also includes 128-bit AES (Advanced Encryption Standard) support and ATA (Advanced Technology Attachment)-password-protection cognizance. Typical active and idle power...

Lithography reduction yields design simplicity

...Texas Instruments last month unveiled its ARM-based DaVinci-branded ICs. The video-focused TMS320DM816x is the first DaVinci-categorized product that TI built on a 40-nm lithography; its precursors use 65- and 90-nm processes. Like TI’s Integra, they combine a Cortex-A8 CPU core and a C674x DSP core. The integrated peripheral mix is also similar to that of Integra, including PCIe (Peripheral Component Interconnect Express) Generation 2, SATA (serial-advanced-technology-attachment) 2.0, GbE (gigabit Ethernet), HDMI (high-definition multimedia interface), CAN (controller-area-network) transceivers...
