Samsung Develops World's Fastest Embedded Memory With eMMC 5.0 Support 77
hypnosec writes "Samsung has announced the world's fastest NAND memory that supports the eMMC 5.0 standard. The new memory chips are based on 10nm class NAND flash technology and feature an interface speed of 400MB/s. Further, the 32GB and 64GB densities have a random read and write speed of 7,000 IOPS (inputs/outputs per second) while the sequential read and write speeds stand at 250MB/s and 90MB/s respectively. The chips will provide for better multitasking, HD video recording, gaming and browsing."

It is about 0% faster for reads than just-released products, while about -50% faster for writes and -70% faster for IOPS.
That doesnt seem to be true. Those produces use many chips to attain their (essentially they are a RAID-0 of many flash chips) , while this is a single chip.

Embedded memory does not mean memory for embedded applications. It means memory that is included as a part of a larger subsystem, sometimes in a multi-chip module (MCM), sometimes in a package-on-package (POP), and the 2 main reasons for it is typically real estate constraints, as well as performance. For instance, this chip is a NAND flash that could go into MCMs that include application processors or basebands in cellphones, or it could be a part of multi-memory packages, where it's combined w/ DDR3 DRAM to provide all the memory that a portable app - such as a cell phone or GPS unit - may need.
I am curious about their 'random read and write' claims - NAND flash does not do random reads or writes: it reads or writes in pages, and so an entire buffer has to be filled before one can write anything. NOR flash is what has the random read and write: one erases in sectors/blocks and programs in bits/bytes/words. Samsung happens to make both, last I checked, so it's not inconceivable that they've combined the 2, and are offering the combination in a single package. But I'd like to know whether that's the case here.
