Resistive random-access memory (RRAM or ReRAM) is a type of nonvolatile memory that works by changing the resistance across a dielectric solid-state material called a memristor. It uses a bipolar resistive switching mechanism where the resistance of the dielectric changes due to the applied voltage. While ReRAM has advantages like high response speed and non-volatility, making it a potential replacement for DRAMs and Flash memories, current disadvantages include integration and reliability issues, high write power needs, and difficulties in controlling filament formation at the nano scale.

1. Re RAM
(Resistive Random
Access Memory)

2. What is RAM?
• Random accessmemory
(RAM) is atype of data
storage used in computers
that is generally located on
the motherboard.
• This type of memory is
volatile.
• It is made up of transistors
and capacitors.

3. What is Resistive RAM?
• Resistive random-access
memory (RRAM or ReRAM) is atype
of nonvolatile memory(NV).
• It is acomputer memory that works
by changing the resistanceacross
adielectric solid-state materialoften
referred toasamemristor.
• Itis apassive two-terminal electronic
device.

4. How does Re RAM work?
• Bipolar Resistive
switching mechanism.
• There is achange inthe
resistance of the
dielectric due to the
applied voltage.
• Memristors, which are
considered tobe asub-
category of resistive
RAM.

5. ADVANTAGES

6. DISADVANTAGES
• Integration and reliability issues
• High write power and Less
Endurance
• High cost and difficulties in fetching
• High operation voltage
• Low uniformity
• Poor device stability
• The filament control at nano scale
is a problem
• Limitations in representing neural
networks
• Switching mechanism is also not
completely established

7. Future Scope:
• The growing adoption of sensors
technology such as wearable and
AI-enabled devices
• AsRRAMhas high responsespeed,
is non-volatile, so it can replace
DRAMsand Flashmemories.
• Dueto high density of nanomaterial
based RRAM,it can store
informations in “terabit” scale or
higher.
