SRAM存储器不需要通过刷新电路就可以保存它内部存储的数据。而DRAM存储器需要一定的时间不断刷新充电，不然内部的数据会丢失，从而可以看出SRAM芯片的性能比较高，功耗也相对较小，但是SRAM也有它的缺点，即它的集成度较低，相同容量的DRAM内存可以设计为较小的体积，但是SRAM却需要很大的体积。同样面积的硅片可以做出更大容量的DRAM，因此SRAM显得更贵。 Part Number Density Organization(bit) Access time(ns) Supply voltage(V) Operating temperature (°C) PackageType R1RW0416DSB-2SR 4Mb x 16 12 3.0 to 3.6 0°C to 70°C TSOPII(44) R1RW0416DSB-2PR 4Mb x 16 12 3.0 to 3.6 0°C to 70°C TSOPII(44) R1RW0416DSB-2PI 4Mb x 16 12 3.0 to 3.6 -40°C to 85°C TSOPII(44) R1RW0416DSB-2LR 4Mb x 16 12 3.0 to 3.6 0 °Cto 70°C TSOPII(44) R1RW0416DSB-0PR 4Mb x 16 10 3.0 to 3.6 0 °Cto 70°C TSOPII(44) R1RW0416DSB-0PI 4Mb x 16 10 3.0 to 3.6 -40°C to 85°C TSOPII(44) R1RW0416DGE-2SR 4Mb x 16 12 3.0 to 3.6 0°C to 70°C SOJ(44) R1RW0416DGE-2PR 4Mb x 16 12 3.0 to 3.6 0°C to 70°C SOJ(44) R1RW0416DGE-2PI 4Mb x 16 12 3.0 to 3.6 -40°C to 85°C SOJ(44) R1RW0416DGE-2LR 4Mb x 16 12 3.0 to 3.6 0 °Cto 70°C SOJ(44) R1RW0408DGE-2PR 4Mb x 8 12 3.0 to 3.6 0 °Cto 70°C SOJ(36) R1RW0408DGE-2PI 4Mb x 8 12 3.0 to 3.6 -40°C to 85°C SOJ(36) R1RW0408DGE-2LR 4Mb x 8 12 3.0 to 3.6 0 °Cto 70°C SOJ(36) R1RW0408DGE-0PR 4Mb x 8 10 3.0 to 3.6 0 °Cto 70°C SOJ(36) R1RP0416DSB-2SR 4Mb x 16 12 4.5 to 5.5 0 °Cto 70°C TSOPII(44) R1RP0416DSB-2PR 4Mb x 16 12 4.5 to 5.5 0 °Cto 70°C TSOPII(44) R1RP0416DSB-2PI 4Mb x 16 12 4.5 to 5.5 -40°C to 85°C TSOPII(44) R1RP0416DSB-2LR 4Mb x 16 12 4.5 to 5.5 0 °Cto 70°C TSOPII(44) R1RP0416DSB-0PR 4Mb x 16 10 4.5 to 5.5 0 °Cto 70°C TSOPII(44) R1RP0416DSB-0PI 4Mb x 16 10 4.5 to 5.5 -40°C to 85°C TSOPII(44) R1RP0416DGE-2SR 4Mb x 16 12 4.5 to 5.5 0 °Cto 70°C SOJ(44) R1RP0416DGE-2PR 4Mb x 16 12 4.5 to 5.5 0 °Cto 70°C SOJ(44) R1RP0416DGE-2PI 4Mb x 16 12 4.5 to 5.5 -40°C to 85°C SOJ(44) R1RP0416DGE-2LR 4Mb x 16 12 4.5 to 5.5 0 °Cto 70°C SOJ(44) R1RP0408DGE-2PR 4Mb x 8 12 4.5 to 5.5 0 °Cto 70°C SOJ(36) R1RP0408DGE-2PI 4Mb x 8 12 4.5 to 5.5 -40°C to 85°C SOJ(36) R1RP0408DGE-2LR 4Mb x 8 12 4.5 to 5.5 0 °Cto 70°C SOJ(36) R1RW0416DGE-0PR 4Mb x 16 10 3.0 to 3.6 0 °Cto 70°C SOJ(44) R1RW0416DGE-0PI 4Mb x 16 10 3.0 to 3.6 -40°C to 85°C SOJ(44) R1RW0408DGE-0PI 4Mb x 8 10 3.0 to 3.6 -40°C to 85°C SOJ(36) R1RP0416DGE-0PI 4Mb x 16 10 4.5 to 5.5 -40°C to 85°C SOJ(44)
