摘要： A memory device, system, and/or method are provided for performing a page state informing function. The memory device may compare one or more row addresses received along with a command, determine the page open/close state according to a page hit or miss generated as a result of comparison, count read or write commands with respect to pages corresponding to a same row address, and determine the page open/close state according to a read or write command number generated as a result of counting. The memory device may determine a page open/close state with respect to a corresponding page based on a page hit/miss and a read or write command number and output a flag signal. The memory device may provide the page open/close state for each channel. A memory controller may establish different page open/close policies for each channel.

摘要： A memory device performing an internal copy operation is provided. The memory device may receive a source address, a destination address, and page size information together with an internal copy command, compares the source address with the destination address, and performs an internal copy operation. The internal copy operation may be an internal block copy operation, an inter-bank copy operation, or an internal bank copy operation. The internal copy operation may be performed with respect to one-page data, half-page data, or quarter-page data, based on the page size information. The memory device may output as a flag signal a copy-done signal indicating that the internal copy operation has been completed.

摘要： In a semiconductor memory device, and in particular in a NAND-type ROM memory cell, the transistors of a memory cell region and a peripheral circuit portion are manufactured to include a first and second impurity regions. The second impurity region has a higher impurity density impurity than the first impurity region. A third impurity region is added which has a higher impurity density and shallower depth than the impurity density of the first impurity region. Accordingly, the conventional transistor structure of the peripheral circuit portion is maintained while the transistors of the memory cell are optimized to have ideal electrical characteristics, including an increased current driving capability.

摘要： Example embodiments relate to a semiconductor memory system which may include a volatile memory and a non-volatile memory that share a common bus, and a method for controlling the operation of the non-volatile memory. The semiconductor memory system may include a non-volatile memory and a memory controller. The non-volatile memory may include a buffer memory that temporarily stores data to be read from or to be written to a memory cell array, and an internal controller. The memory controller may transmits a mode signal to the non-volatile memory in response to a control signal, the control signal corresponds to either a read mode or a write mode to be applied to the non-volatile memory. In response to the mode signal, the internal controller may control the data to be read to be stored in the buffer memory, if the read mode is to be applied, and the internal controller may control the buffer memory to stand-by until a write command is received, if the write mode is to be applied.
