Memory and Storage Questions

• Due to their ability to be easily erased and reused, magnetic memory devices are widely used for RAM.
• Erasing or programming a flash memory device is a one-step operation.
• Static RAMs (SRAMs) use internal capacitors as basic storage elements.
• The time delay called access time, tac, is a measure of the ROM's operating speed.
• ROM is a type of memory in which data are stored permanently or semipermanently.
• To reduce the number of pins on high-capacity DRAM chips, address ________ is used so that a single pin can accommodate two different address bits.
• Dynamic RAMs store information by using ________.
• The TMS44100 has ________ address inputs.
