2. EEPROM - Wikipedia

   en.wikipedia.org/wiki/EEPROM

   A typical EEPROM serial protocol consists of three phases: OP-code phase, address phase and data phase. The OP-code is usually the first 8 bits input to the serial input pin of the EEPROM device (or with most I²C devices, is implicit); followed by 8 to 24 bits of addressing, depending on the depth of the device, then the read or write data.

3. Byte addressing - Wikipedia

   en.wikipedia.org/wiki/Byte_addressing

   The basic unit of digital storage is a bit, storing a single 0 or 1. Many common instruction set architectures can address more than 8 bits of data at a time. For example, 32-bit x86 processors have 32-bit general-purpose registers and can handle 32-bit (4-byte) data in single instructions. However, data in memory may be of various lengths.

4. Content-addressable memory - Wikipedia

   en.wikipedia.org/wiki/Content-addressable_memory

   Content-addressable memory (CAM) is a special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory or associative storage and compares input search data against a table of stored data, and returns the address of matching data. [1]

5. Bus (computing) - Wikipedia

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

   An address bus is a bus that is used to specify a physical address. When a processor or DMA-enabled device needs to read or write to a memory location, it specifies that memory location on the address bus (the value to be read or written is sent on the data bus). The width of the address bus determines the amount of memory a system can address.

6. NVDIMM - Wikipedia

   en.wikipedia.org/wiki/NVDIMM

   Many "non-volatile" products use volatile memory during normal operation and dump the contents into non-volatile memory if the power fails, using an on-board backup power source. Volatile memory is faster than non-volatile; it is byte-addressable; and it can be written to arbitrarily, without concerns about wear and device lifespan. However ...

7. Word addressing - Wikipedia

   en.wikipedia.org/wiki/Word_addressing

   If the web browser is running on a computer with 32-bit addresses and byte-addressable memory, the address space will cover 4 Gigabytes of memory, which is insufficient. The browser will either be unable to display this page, or it will need to be able to opportunistically move some of the data to slower storage, which will substantially hurt ...

8. AVR microcontrollers - Wikipedia

   en.wikipedia.org/wiki/AVR_microcontrollers

   Almost all AVR microcontrollers have internal EEPROM for semi-permanent data storage. Like flash memory, EEPROM can maintain its contents when electrical power is removed. In most variants of the AVR architecture, this internal EEPROM memory is not mapped into the MCU's addressable memory space.

9. Non-volatile memory - Wikipedia

   en.wikipedia.org/wiki/Non-volatile_memory

   Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. In contrast, volatile memory needs constant power in order to retain data.
