What is Flash Memory with its Types, Examples, and Devices?

1
What is Flash Memory
Flash Memory was introduced by Dr. Fujio Masuoka
in 1980. Flash memory is also known as
electronically erasable programmable read only
memory (EEPROM), because in which piece of  code
like as programming can be write and erased by
electrically.

Types of Flash Memory
Flash Memory is divided into two types based on
using technology, such as NOR Flash Memory
NOR flash memory is executed into XIP Memory,
that means all programs and instructions are
saved into NOR flash, and these programs are
executed itself with using of NOR flash without
accessing any copied data into Main Memory. NAND
Flash Memory NAND flash is best option to access
much such as block devices, like as Hard Disk.
If, you needs to higher data storage capacity
then NAND flash memory is great selection for
you. It delivers tech higher densities and
enlarges capacity with affordable price. It is
capable to erase, sequential writes and
sequential reads with higher speed.

Four Types of Flash Memory as Per User
Requirements
Traditional Flash Storage In the traditional
flash storage, we used the HDD storage
techniques, and this technique delivers the
cost-effective capacity so due to that, users
have flexibility to scale this system. Due to
unreliable, several experts suggest that this
storage capacity is not capable to store data
more than 50. Server Flash Memory Server Flash
Memory prefers the cache storage capacity because
it allows to users access data with higher speed
along with lower storage capacity. But, now it is
getting more popularity because its property is
adding IOPS, and it grows flash memory with using
functioning parallel host application, so due to
this big advantage now mostly peoples first
preferred selection is Server Flash Memory. The
All Flash Array All Flash Array contains the
best consistent storage capacity. It works as the
solid state storage because it allows to multiple
flash memory drivers, instead of spinning the
hard disk drives. Hybrid Array Hybrid Array
flash memory is known as the Intelligent Caching
Solution. It delivers you sub millisecond access
for cached data, and it leverages HHD storage
capacity.

Examples of Flash Memory
USB Flash Drive USB flash drive is also known
as USB thumb drive, USB stick or Pen drive. It is
light weight portable storage device, and it is
used as Plug and Play. Now these days, USB
flash drive is totally replaced with compact
disc, because you can plug it into USB port of
the computer system then USB flash drive is
capable to store most important files, folders or
data. CF (Compact Flash) Compact Flash is also
a different type of flash memory, but this memory
is mostly preferred in the digital cameras for
holding images. It is used also other devices
like as portable music players and PDA.

Examples of Flash Memory
M.2 SSD M.2 SSD stands for M.2 Solid-State
Drive, and it is used in internally mounted
storage expansion cards as per the computer
industry specification. Memory Card Memory
card is also known as Flash Memory Card, and
it is storage medium of different types of data
such as images, video or text. Memory card is
mostly used into various types of secondary
memory such as digital camcorders, handheld
computers, MP3 players, printer, digital cameras
and more.

Examples of Flash Memory
MMC MMC stands for Multi Media Card, and it
is small type of memory card that is used as
flash memory into several portable devices like
as PCs, music media player, smart phones, video
camcorders, car navigation, and more. NVMe
NVMe stands for Non-Volatile Memory Express,
and it is used as host controller interface and
storage protocol for flash and next generation
SSDs which provides the higher throughput and
fastest response times for different types of
enterprise workloads.

Examples of Flash Memory
SDHC Card SDHC stands for Secure Digital High
Capacity card, and it is advance version of the
SD card along with storage capacity up to 32
GB. SmartMedia Card It is a data storage
medium device, and it contains the flash memory
that helps to hold data. SmartMedia Card was
introduced by the Toshiba with storage capacity
from 2 MB to 128 MB, and its physical dimensions
of 45mm x 37mm x .76mm.

Examples of Flash Memory
Sony Memory Stick Sony Memory Stick is also
flash memory card. Sony Memory Stick was
introduced by Sony in 1998 for digital storage in
some portable devices such as digital cameras,
video camcorder, and other devices. SD Card SD
card is also known as Secure Digital Memory
Card, and it is part of the flash memory. SD
card was designed by Panasonic, Toshiba and
SanDisk in 1999 for data storage in the cameras
and phones.

Examples of Flash Memory
SSD SSD stands for Solid-State Drive, and it
is data storage medium. SSD is a non-volatile
memory to store and access any types of data. It
does not contain any moving parts, so it delivers
the faster access time, noiseless operation,
higher reliability, and lower power consumption.
xD Picture Card Its full form is EXtreme
Digital Picture Card, and it is designed by FUji
and Olympus, in 2002 for using in the digital
cameras.

Advantages of Flash Memory

• There are several benefits of flash memory, such
  as
• It saves all data when power is getting turn off.
• Higher speed of read and write than traditional
  memory.
• Smaller size
• Portability
• Consume less power compare to traditional memory.
• Low chances to damage

11
Disadvantages of Flash Memory

• Here, we will spread light on few limitations of
  flash memory, such as
• Flash memory contains a limited number of write
  and erases cycles before failing.
• Flash memory does not contain any
  write-protection mechanism.
• It is more costly than hard disk (Cost per MB)
• Easy to lose due to its smaller size
• Writing (1-gt0) is costly.
• Erasing (0-gt1) is more costly.
