Memory Stick: Sony, SanDisk: Standard 1998 128 MB Slim and narrow (50 mm × 21.5 mm × 2.8 mm), optional DRM, up to 128 MB PRO 2003 4 GB (not to scale) Slim and narrow (50 mm × 21.5 mm × 2.8 mm), swifter, optional DRM, up to 4 GB Duo 2003 128 MB Compact (31 mm × 20 mm × 1.6 mm), optional DRM, up to 128 MB PRO Duo 2002–2006
The Memory Stick Micro (M2) measures 15 × 12.5 × 1.2 mm (roughly one-quarter the size of the Duo) with 64 MB, 128 MB, 256 MB, 512 MB, 1 GB, 2 GB, 4 GB, 8 GB, and 16 GB capacities available. The format has a theoretical limit of 32 GB and maximum transfer speed of 160 Mbit/s.
All three concepts became obsolete once flash memory prices became lower and their capacities became higher by 2006. [20] New products of Sony (previously only using Memory Stick) and Olympus (previously only using XD-Card) have been offered with an additional SD-Card slot beginning in 2010. [23] Effectively the format war has turned in SD-Card ...
Four sticks of G.SKILL TridentZ Memory. G.SKILL is known for its range of DDR, [4] DDR2, [5] DDR3, [6] DDR4 [6] and DDR5 [7] computer memory. RAM is available in single-channel, dual-channel, triple-channel and quad-channel packs for desktops, workstations, HTPC, as well as netbooks and laptops.
A flash drive (also thumb drive, memory stick, and pen drive/pendrive) [1] [note 1] is a data storage device that includes flash memory with an integrated USB interface. A typical USB drive is removable, rewritable, and smaller than an optical disc , and usually weighs less than 30 g (1 oz).
1 GB PC3200 non-ECC modules are usually made with 16 512 Mbit chips, 8 on each side (512 Mbits × 16 chips) / (8 bits (per byte)) = 1,024 MB. The individual chips making up a 1 GB memory module are usually organized as 2 26 8-bit words, commonly expressed as 64M×8. Memory manufactured in this way is low-density RAM and is usually compatible ...
PC2-5300 DDR2 SO-DIMM (for notebooks) Comparison of memory modules for desktop PCs (DIMM) Comparison of memory modules for portable/mobile PCs (SO-DIMM) The key difference between DDR2 and DDR SDRAM is the increase in prefetch length. In DDR SDRAM, the prefetch length was two bits for every bit in a word; whereas it is four bits in DDR2 SDRAM.
DDR5 octuples the maximum DIMM capacity from 64 GB to 512 GB. [8] [3] DDR5 also has higher frequencies than DDR4, up to 8GT/s which translates into 64 GB/s (8 gigatransfers/second × 64-bits/module / 8 bits/byte = 64 GB/s) of bandwidth per DIMM. Rambus announced a working DDR5 dual in-line memory module (DIMM) in September 2017.
