Windows Vista allows only one device to be used, while Windows 7 allows multiple caches, one per device, up to a total of 256 GB. [5] ReadyBoost compresses and encrypts all data that is placed on the flash device with AES-128; Microsoft has stated that a 2:1 compression ratio is typical, so a 4 GB cache would usually contain 8 GB of data.

Flashrom is a software utility published under an open source license that can detect, read, verify, erase, or write EEPROMs using interfaces such as the Low Pin Count (LPC), FWH, parallel, and Serial Peripheral Interface (SPI). It can be used to flash firmware images such as BIOS or coreboot, or to backup existing firmware.
Storage: USB flash drives are hard to track physically, being stored in bags, backpacks, laptop cases, jackets, trouser pockets or left at unattended workstations. Usage: tracking corporate data stored on personal flash drives is a significant challenge; the drives are small, common and constantly moving.
In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module.Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.

An assortment of flash drives Transcend JetFlash from 2014. A flash drive is a portable computer drive that uses flash memory. Flash drives are the larger memory modules consisting of a number of flash chips. A flash chip is used to read the contents of a single cell, but it can write entire block of cells.
Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level depending on ...
The USB mass storage device class (also known as USB MSC or UMS) is a set of computing communications protocols, specifically a USB Device Class, defined by the USB Implementers Forum that makes a USB device accessible to a host computing device and enables file transfers between the host and the USB device. To a host, the USB device acts as an ...
