Exam 5: Internal Memory

Semiconductor memory comes in packaged chips.

Theoretically,a DDR module can transfer data at a clock rate in the range of __________ Mbps.

In a _________,binary values are stored using traditional flip-flop logic-gate configurations.

An error-correcting code enhances the reliability of the memory at the cost of added complexity.

Flash memory is only used for internal memory applications.

RAM must be provided with a constant power supply.

The _________ exchanges data with the processor synchronized to an external clock signal and running at the full speed of the processor / memory bus without imposing wait states.

NOR memory is better suited for external memory such as USB flash drives and memory cards.

A DDR3 module transfers data at a clock rate of __________ Mbps.

_________ can be caused by power supply problems or alpha particles.

Which of the following memory types are nonvolatile?

________ increases the prefetch buffer size to 8 bits.

With __________ the data transfer is synchronized to both the rising and falling edge of the clock,rather than just the rising edge.

__________ can be caused by harsh environmental abuse,manufacturing defects,and wear.

The SDRAM performs best when it is transferring large blocks of data sequentially such as for word processing,spreadsheets,and multimedia.

The traditional __________ chip is constrained both by its internal architecture and by its interface to the processor's memory bus.

A characteristic of ROM is that it is volatile.

In earlier computers the most common form of random-access storage for computer main memory employed an array of doughnut-shaped ferromagnetic loops referred to as __________.

One distinguishing characteristic of memory that is designated as _________ is that it is possible to both read data from the memory and to write new data into the memory easily and rapidly.

A __________ contains a permanent pattern of data that cannot be changed,is nonvolatile,and cannot have new data written into it.
