摘要： A semiconductor memory in accordance with the present invention includes a data path including a plurality of hierarchical stages, each stage including a bit data rate which is different from the other stages. At least two prefetch circuits are disposed between the stages. The at least two prefetch circuits include at least two latches for receiving data bits and storing the data bits until a next stage in the hierarchy is capable of receiving the data bits. The at least two prefetch circuits are coupled between stages such that an overall data rate per stage between stages are substantially equal. Control signals control the at least two latches such that prefetch circuits maintain the overall data rate between the stages.

摘要： A memory system that employs simultaneous activation of at least two dissimilar memory arrays, during a data manipulation, such as read or write operations is disclosed. An exemplary embodiment includes a memory system containing a plurality of arrays, each in communication with a common controller, wherein the arrays are activated by different supply voltage (Vdd). When a processor sends a command to retrieve or write data to the memory system, two or more arrays are addressed to supply the required data. By proper partitioning of the data between dissimilar arrays, the efficiency of data reading is improved.

摘要： The semiconductor memory includes a memory cell array (10) of memory cells arranged in rows and columns, and a plurality of diagonal bit lines (BLP.sub.1 -BLP.sub.N) arranged in a pattern that changes horizontal direction along the memory cell array to facilitate access to said memory cells. The bit lines are arranged non-orthogonal to a plurality of dual word lines (WL.sub.1 -WL.sub.M), where each dual word line includes a master word line (MWL.sub.i) at a first layer and a plurality of local word lines (LWL.sub.1 -LWL.sub.X) at a second layer. The local word lines are connected to the master word line of a common row via a plurality of spaced electrical connections (29), e.g., electrical contacts in a "stitched" architecture, and each local word line is connected to plural memory cells (MC). The electrical connections run in substantially the same pattern along the memory cell array as the bit lines.

摘要： A random access memory (RAM) included in an integrated circuit and particularly a synchronous dynamic RAM (SDRAM) having a maskable data input. The SDRAM includes an xy data input register receiving a burst x bits long and y bits wide corresponding to the number of data lines (DQs). An xy mask register receives a corresponding mask bit for each received data bit, each mask bit indicating whether the corresponding data bit is stored in the SDRAM array. An enable buffer receives data outputs from the xy data input register and passes the individual data outputs to the array depending on corresponding mask states stored in the xy mask register. The mask register is preferably set to a masked state. Un masking occurs when an enable signal is asserted on a bit by bit basis. This allows the remaining bits within the burst length to be in a masked state when a write burst interrupt command is asserted. During an input prefetch, an interrupt may occur causing any received portion of the burst or prefetch to be stored in the array without disturbing memory locations corresponding to the balance or remaining bits of the prefetch.
