2. Flash memory - Wikipedia

   en.wikipedia.org/wiki/Flash_memory

   Flash memory [3] is used in computers, PDAs, digital audio players, digital cameras, mobile phones, synthesizers, video games, scientific instrumentation, industrial robotics, and medical electronics. Flash memory has a fast read access time but it is not as fast as static RAM or ROM. In portable devices, it is preferred to use flash memory ...

3. Semiconductor memory - Wikipedia

   en.wikipedia.org/wiki/Semiconductor_memory

   Semiconductor memory is a digital electronic semiconductor device used for digital data storage, such as computer memory. It typically refers to devices in which data is stored within metal–oxide–semiconductor (MOS) memory cells on a silicon integrated circuit memory chip .

4. Non-volatile memory - Wikipedia

   en.wikipedia.org/wiki/Non-volatile_memory

   Flash memory is a solid-state chip that maintains stored data without any external power source. It is a close relative to the EEPROM; it differs in that erase operations must be done on a block basis, and its capacity is substantially larger than that of an EEPROM. Flash memory devices use two different technologies—NOR and NAND—to map data.

5. Memory cell (computing) - Wikipedia

   en.wikipedia.org/wiki/Memory_cell_(computing)

   Logic circuits without memory cells are called combinational, meaning the output depends only on the present input. But memory is a key element of digital systems. In computers, it allows to store both programs and data and memory cells are also used for temporary storage of the output of combinational circuits to be used later by digital systems.

6. Charge trap flash - Wikipedia

   en.wikipedia.org/wiki/Charge_trap_flash

   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 ...

7. Comparison of memory cards - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_memory_cards

   Packages the flash memory, currently soldered in shipping smartphones, into a removable card form factor. Uses the SCSI command set including queuing. The electrical interface makes use of differential signaling , which enables high bus speeds and robustness under noisy conditions and reduced pin count (compared to parallel bus alternatives ...
