FULL PAGE INCREMENT/DECREMENT BURST FOR DDR SDRAM/SGRAM

摘要

A dual-data rate (DDR) synchronous dynamic random access memory (SDRAM)/synchronous graphic random access memory (SGRAM), having a full-page increment/decrement burst mode. In one embodiment, the DDR SDRAM/SGRAM includes a memory array and a logic circuitry coupled thereto. The memory array is addressable by even and odd word addresses. The logic circuitry has a burst increment mode to access the array starting at an even word address and a burst decrement mode to access the array starting at an odd word address.
