Abstract
In a random access memory, a dynamic memory array is associated with static data buffers. Each static data buffer is connected to the memory array to receive and store a row of data from any addressed row of the array. When an address is received, it is compared with addresses stored in registers and associated with the data stored in the static buffers. Where there is a match, a controller is able to select the data buffer in which the row of data is stored for a column strobe operation without the need for a row address strobe operation. The resultant system provides for a set associative cache coupled to the dynamic memory array. Further, the comparison can be made of virtual addresses for a cache system which responds to virtual addresses.
