DDR5 has existed in a few different forms in the past year or two, but this past week brought news of the first JEDEC-compliant memory chip for future DDR5 implementations. As usual with new memory standards, frequency is expected to increase (and timings will likely loosen) significantly with the new generation, something we talk about in today's list of news items for the week. Also in that list, we talk ongoing CPU shortages for CPUs, Apple's T2 security co-processor and its impact on right to repair, and official mouse/keyboard support on the Xbox.

Taiwan Semiconductor Manufacturing Co. (TSMC) has set sights on building a new $15.7 billion facility geared towards the 5 and 3 nanometer chip processes, eyes set for future process nodes. TSMC is the world’s biggest chip maker by revenue, accounting for 55% of the market share. TSMC’s deep-pocketed clients include Qualcomm, nVidia, and Apple, whose iPhone 7 launch was especially pivotal in the record quarter to quarter profits TSMC has been reporting, as TSMC produces the A10 processor for the iPhone 7.
Taiwan Semiconductor houses its base of operations in Northern Taiwan, where several of their fabs are located. This is in addition to leading-edge fabs in Southern Taiwan and Central Taiwan, not to mention manufacturing bases in China.
5MB of storage once required 50 spinning platters and a dedicated computer, demanding a 16 square-foot area for its residence. The first hard drive wasn't particularly fast at 1200RPM and with seek latencies through the roof (imagine a header seeking between 50 platters) – but it was the most advanced storage of the time.
That device was the IBM 305 RAMAC, its converted cost was a $30,000 monthly lease, and single instruction execution required between 30ms and 50ms (IRW phases). The IBM 305 RAMAC did roughly 100,000 bits per second, or 0.0125MB/s. Today, the average 128GB microSD card costs ~$50 – one time – and executes read/write instructions at 671,000,000 bits per second, or 80MB/s. And this is one of our slowest forms of Flash storage. The microSD card is roughly the size of a fingernail (32x24x2.1mm), and filling a 16 square-foot area with them would yield terabytes upon terabytes of storage.
The 305 RAMAC was a creation of 1956. Following last week's GTC conference, we had the opportunity to see the RAMAC and other early computing creations at the Computer History Museum in Mountain View, California. The museum encompasses most of computing history, including the abacus, early Texas Instruments advanced calculators (like the TI-99), and previously housed a mechanical Babbage Machine computer from the 1800s. In our recent tour of the Computer History Museum, we focused on the predecessors to modern computing – the first hard drive, first supercomputers, first transistorized computers, mercury and core memory, and vacuum tube computing.
