Semiconductor Memory Questions

• Memory technologies: Which type of semiconductor memory uses a single MOSFET (1T) together with a storage capacitor as its basic memory cell structure?
• Memory timing fundamentals: The access time t_acc (read access time) of a memory IC is primarily governed by which internal feature of the chip?
• DRAM system design: What is the principal advantage of address multiplexing in dynamic RAM (DRAM) devices?
• Nonvolatile memory comparison: Which statement best captures the key advantage(s) of EEPROM over EPROM for in-circuit updates?
• Definition check: Which statement best describes nonvolatile memory behavior with respect to power removal?
• Read-only memory (ROM): Select the most accurate description of ROM usage and data retention in digital systems.
• Built-in test: A computerized self-diagnostic that verifies the integrity of a ROM image most commonly uses which method?
• Volatility concept: Memory that loses its contents as soon as power is removed is classified as what type of memory?
• Programmable ROM types: Select the best description of a fusible-link PROM device and its programmability.
• RAM performance metrics: Which RAM timing parameters most directly determine the memory's operating speed in sustained operation (read and write cycles)?
• Digital memory addressing: If a memory device provides twelve (12) address lines from the processor or address decoder, how many unique storage locations (addresses) can it select in total?
• Nonvolatile memory technologies: Which memory type is nonvolatile and supports erase/program operations in blocks or sectors (rather than erasing one byte at a time)?
• Static versus dynamic memory: Which statement best describes static (SRAM) memory devices in terms of data retention and refresh behavior?
• SRAM vs. DRAM cell complexity — assess the statement: “An SRAM storage cell is less complex than a DRAM storage cell.”
• ROM terminology — assess the statement: “Storing a binary word into a ROM device is called burning in.”
• ROM acronym — verify the expansion: “ROM stands for read-only memory.” Is this standard definition correct in digital electronics?
• Semiconductor memory fundamentals — “memory configuration” refers to how storage bits are organized internally (e.g., word width, number of addresses, and row/column arrangement). Evaluate this statement.
• Static RAM (SRAM) data retention — does SRAM require periodic refresh every few milliseconds to avoid data loss, like DRAM does?
• Storage density — this term compares one memory device’s ability to store information with another (bits per chip/area/package). Is that an appropriate definition?
• Programmable Read-Only Memory (PROM) volatility — are PROM devices considered volatile (i.e., do they lose data when power is removed)?
