2. Flash memory - Wikipedia

   en.wikipedia.org/wiki/Flash_memory

   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 ...

3. Non-volatile memory - Wikipedia

   en.wikipedia.org/wiki/Non-volatile_memory

   Non-volatile memory typically refers to storage in memory chips, which store data in floating-gate memory cells consisting of floating-gate MOSFETs (metal–oxide–semiconductor field-effect transistors), including flash memory storage such as NAND flash and solid-state drives (SSD).

4. Solid-state storage - Wikipedia

   en.wikipedia.org/wiki/Solid-state_storage

   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.

5. Charge trap flash - Wikipedia

   en.wikipedia.org/wiki/Charge_trap_flash

   This was the first form of non-volatile memory based on the injection and storage of charges in a floating-gate MOSFET, [5] which later became the basis for EPROM (erasable PROM), EEPROM (electrically erasable PROM) and flash memory technologies. [6] The charge-trapping concept was first presented by John Szedon and Ting L. Chu in 1967 ...

6. Solid-state drive - Wikipedia

   en.wikipedia.org/wiki/Solid-state_drive

   Most SSDs use non-volatile NAND flash memory for data storage, primarily due to its cost-effectiveness and ability to retain data without a constant power supply. NAND flash-based SSDs store data in semiconductor cells, with the specific architecture influencing performance, endurance, and cost.

7. Non-volatile random-access memory - Wikipedia

   en.wikipedia.org/wiki/Non-volatile_random-access...

   Non-volatile random-access memory (NVRAM) is random-access memory that retains data without applied power. This is in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM), which both maintain data only for as long as power is applied, or forms of sequential-access memory such as magnetic tape, which cannot be randomly accessed but which retains data ...

8. Read-only memory - Wikipedia

   en.wikipedia.org/wiki/Read-only_memory

   EAROM may be used as non-volatile storage for critical system setup information; in many applications, EAROM has been supplanted by CMOS RAM supplied by mains power and backed up with a lithium battery. Flash memory (or simply flash) is a modern type of EEPROM invented in 1984. Flash memory can be erased and rewritten faster than ordinary ...

9. External storage - Wikipedia

   en.wikipedia.org/wiki/External_storage

   Memory stick is an integrated circuit designed to serve as a storage and transfer medium for digital data. It can store data in various form as text, graphics, digital images etc. transfer of data is possible between devices having memory stick slots. Memory sticks are available in various storage sizes ranging from 4 GB to 64 GB.
