摘要： A memory device includes a memory cell array, a row decoding section, a K-bit prefetch section and an output buffer section. The row decoding section decodes a row address in response to a first clock, to activate one of the word lines corresponding to the decoded row address. The K-bit prefetch section decodes a column address in response to a second clock and prefetches K data from K memory cells connected to the activated word line and corresponds to the decoded column address, in response to a second clock, where a frequency of the second clock is 1/M of that of the first clock. The output buffer section outputs the K prefetched data as a data stream in response to a third clock. Therefore, a burden from the physical limit of the access speed may be alleviated when the data I/O speed is increased.

摘要： A refresh address is generated with a refresh period for refreshing a memory device with refresh leveraging. A respective refresh is performed on a weak cell having a first address when the refresh address is a second address instead of on a first strong cell having the second address. A respective refresh is performed on one of the first strong cell or a second strong cell having a third address when the refresh address is the third address. Address information is stored for only one of the first, second, and third addresses such that memory capacity may be reduced. In alternative aspects, a respective refresh is performed on one of a weak cell, a first strong cell, or a second strong cell depending on a flag when the refresh address is any of at least one predetermined address to result in refresh leveraging.

摘要： A phase-locked-loop (PLL) circuit is provided. The PLL circuit includes a phase/frequency detector, a digital filter, a digital low pass filter (LPF), a digitally controlled oscillator (DCO), and a frequency divider. The digital LPF performs a low-pass-filtering on least significant bits of first digital data in a digital mode and generates filtered second digital data. The DCO performs a digital-to-analog conversion on the second digital data and most significant bits of the first digital data to generate a first signal, generates an oscillation control signal based on the first signal, and generates an output clock signal oscillating in response to the oscillation control signal.

摘要： A memory system includes a controller for generating a control signal and a primary memory for receiving the control signal from the controller. A secondary memory is coupled to the primary memory, the secondary memory being adapted to receive the control signal from the primary memory. The control signal defines a background operation to be performed by one of the primary and secondary memories and a foreground operation to be performed by the other of the primary and secondary memories. The primary memory and the secondary memory are connected by a point-to-point link. At least one of the links between the primary and secondary memories can be an at least partially serialized link. At least one of the primary and secondary memories can include an on-board internal cache memory.
