In addition, in the secure distance identification platform for application type analysis, the data storage device may be selected as an SGRAM chip.
SGRAM is an abbreviation of Synchronous Graphics DRAM, and means that Synchronous Graphics RAM is a video memory specially designed for a video card, is a video memory with stronger Graphics read-write capability, and is formed by improving SDRAM. The method improves the defect of low video memory transmission rate of low performance in the past, and creates conditions for improving the performance of the display card. The SGRAM reads and writes data not one by one, but uses a Block as a unit, thereby reducing the times of reading and writing the whole memory and improving the efficiency of a graphic controller. But the design and manufacturing cost is higher, and more, the display card is applied to higher-end display cards at that time. At present, such a video memory is not adopted by manufacturers and is replaced by a DDR video memory. SDRAM, Synchronous dynamic random access memory DRAM (SDRAM), was once the most widely used memory type in PC computers, and even today SDRAM still has a place in the market. Since it is a "synchronous dynamic random access memory," it means that its operating speed is synchronized with the system bus speed. The SDRAM memory is divided into different specifications of PC66, PC100, PC133, etc., and the number following the specification represents the maximum normal operating system bus speed of the memory, such as PC100, which means that the memory can operate synchronously in a computer with a system bus of 100 MHz. Synchronous with the system bus speed, namely synchronous with the system clock, thus avoiding unnecessary waiting period and reducing data storage time. Synchronization also allows the memory controller to know during which clock period the data is being requested and therefore the data can begin to be transferred during the pulse rise period. SDRAM uses 3.3 volt working voltage, 168Pin DIMM interface, and the bandwidth is 64 bits. SDRAM is not only used in memories, but also in video memories. SDRAM can work with CPU synchronization, does not have the latency cycle, reduces data transmission delay.
