Which of the following statements are true? Check all that apply. 1) DRAM memories retain information even when no power is supplied because they incorporate circuitry that periodically refreshes the information. 2) DRAM basic cell has fewer transistors than the SRAM one and therefore, DRAM memories may have a larger storage capacity than the SRAM memories. 3) OTP ROMs are non-volatile. 4) In a Read/Write memory, bit-lines transmit the information to be stored in memory cells, while word-lines transmit the Read/Write command. 5) A 220 x 16 words memory has a 16-bit data bus and a 220-bit address bus. 6) Flash memories store information in the absence of power supply because they incorporate circuitry that periodically refreshes the information.
Develop a 64-bit wide memory interface that contains SRAM at locations (EEFE80000- EEFEFFFFF) and EPROM at locations (FFZFO0000-FFZFFFFFF) for the Pentium II Hp using 16L8 as a PLA decoder circuit. For the hypotheses 80xxxx Hp, if we decide to modify the 64-bit wide memory to 32-bit, suggest the memory locations for both memory types and develop the memory interfacing circuit. If you know that the required time for reading from any single EPROM chip is 950 ns and the clock is up-clocked at 15 MHz, how many wait states are required for doing that? Sketch the required circuit for generating the desired number of wait states.
