Memory fundamentals — In static RAM (SRAM), the term "static" does not mean non-volatile. Evaluate the statement: "Static memory will maintain storage even if power is removed."

Introduction:
This item probes a common misconception about static random-access memory (SRAM). Many learners assume the word "static" implies that data is retained without power, but in digital electronics, "static" and "dynamic" refer to how data is maintained while power is applied. We will clarify why the statement "Static memory will maintain storage even if power is removed" is incorrect and contrast SRAM with non-volatile memories.

Given Data / Assumptions:

• Static memory here refers to SRAM used in caches and embedded systems.
• Non-volatile examples include ROM, EPROM, EEPROM, and flash.
• We consider normal operation without auxiliary batteries or supercapacitors.

Concept / Approach:
In SRAM, each bit is stored by a bistable element (commonly a 6-transistor cell) that actively holds a 0 or 1 as long as Vcc is present. "Static" means the cell does not require periodic refresh cycles like DRAM does; it does not mean the memory is persistent without power. When power is removed, the transistors no longer bias the bistable nodes, and the stored state is lost. Persistence without power is the defining property of non-volatile memory, not SRAM.
