An electrophoretic mobility shift assay (EMSA) or mobility shift electrophoresis, also referred as a gel shift assay, gel mobility shift assay, band shift assay, or gel retardation assay, is a common affinity electrophoresis technique used to study protein–DNA or protein–RNA interactions. This procedure can determine if a protein or mixture ...
Many past microcontrollers included both (flash memory for the firmware and a small EEPROM for parameters), though the trend with modern microcontrollers is to emulate EEPROM using flash. As of 2020, flash memory costs much less than byte-programmable EEPROM and is the dominant memory type wherever a system requires a significant amount of non ...
Flashcache works by using flash memory, a USB flash drive, SD card, CompactFlash or any kind of portable flash mass storage system as a write-back persistent cache. An internal SSD can also be used for increasing performance. [3]
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 ...
Charge trap flash (CTF) is a semiconductor memory technology used in creating non-volatile NOR and NAND flash memory. It is a type of floating-gate MOSFET memory technology , but differs from the conventional floating-gate technology in that it uses a silicon nitride film to store electrons rather than the doped polycrystalline silicon typical ...
An illustration of the write amplification phenomenon in flash-based storage devices. Over time, advancements in central processing unit (CPU) speed has driven innovation in secondary storage technology. [7] One such innovation, flash memory, is a non-volatile storage medium that can be electrically erased and reprogrammed.
Each flash module within a FlashSystem incorporates enterprise multi-level cell or single-level cell flash chips and FPGAs that provide IBM Variable Stripe RAID data protection as well as standard flash memory controller functions. IBM claims that these architectural attributes provide strong performance, reliability, and efficiency. [4]
A flash emulator or flash memory emulator is a tool that is used to temporarily replace flash memory or ROM chips in an embedded device for the purpose of debugging embedded software. Such tools contain Dual-ported RAM , one port of which is connected to a target system (i.e. system, that is being debugged), and second is connected to a host (i ...
