In early age computing arena, memory was deployed volatile only, and memories were classified static or random;

Commonly; after year 2000 ; memory has been used both volatile and non-volatile [storage + memory]; "volatile only" means WHILE power is on, temporary memory storage space available to store / to keep / to retrieve / to process instructions, also see: assembly mnemonics ... , and WHILE power is off, those memory storage spaces become unavailable; "Non-volatile" means permanent AND temporary memory storage space available regardless of whether power is on or off; Sometime;

memory and storage are file system dependent AND independent;

(Overview of memory: (R / W memory OR RAM (DRAM) (SRAM))  (ROM (Mask ROM; also called Fuse ROM) (P ROM (E P ROM) (EE P ROM)) (Flash Memory) (F RAM)));

IFF testing, add your define memory into above table; defining your own OEM module into above table by adding a row simply; automatic adjusting bus' speed, e.g. 1 second EDO RAM with 32 KB, e.g. 1 pi co second TI MM with 8 TB, e.g. 2D green color I r o RAM with 1 TB; your newly testing HARDWARE memory module, working with basic in numerological dimension;

After reading above table; notice that storage and memory cannot be separated; and they are similar to each other; But the following might be different:

( Storage (Slower (Read) (Write)) (Lesser cost) (Larger volume)                     )
( Memory (Faster (Read) (Write)) (Higher cost) (Smaller volume)                     )
