EEPROM capabilities: Which set of operations is supported by a typical byte-erasable EEPROM device?

Introduction / Context:Nonvolatile memories differ in their erase/write granularity. EEPROMs (Electrically Erasable Programmable ROMs) allow erasing and writing at the byte level, unlike UV-EPROMs (chip erase with UV light) or many NOR/NAND flash memories (block or sector erase).

Given Data / Assumptions:

• Device: classic EEPROM (not flash).
• Granularity: byte erase and byte write are supported.
• Chip-erase is generally a flash feature, not standard for byte-addressable EEPROM.

Concept / Approach:Match the definition: EEPROM supports random byte write and byte erase alongside standard read operations. Therefore, options that include 'chip erase' are more indicative of EPROM (UV) or Flash devices rather than EEPROM.

Step-by-Step Solution:

Verification / Alternative check:Consult datasheets for 24xx/28xx series EEPROMs: specify byte write/erase cycles and endurance, not chip-wide erase requirements.
