Which of the following statements are true? Check all that apply.
a. In a Read/Write memory, bit-lines transmit the information to be stored in memory cells, while word-lines transmit the Read/Write command
b. DRAM basic cell has fewer transistors than the SRAM one and therefore, DRAM memories may have a larger storage capacity than the SRAM memories.
c. A 2²⁰ x 16 words memory has a 16-bit data bus and a 2²⁰-bit address bus.
d. Flash memories store information in absence of power supply because they incorporate circuitry that periodically refreshes the information.
e. OTP ROMs are non-volatile
f. DRAM memories retain information even when no power is supplied because they incorporate circuitry that periodically refreshes the information.
