AP MEMORY愛(ài)普科技股份有限公司(TWSE:6531)成立於2011年，營(yíng)運(yùn)總部位于臺(tái)灣新竹，是一家無(wú)晶圓廠客制化記憶體設(shè)計(jì)和IP解決方案的半導(dǎo)體公司。公司研發(fā)實(shí)力強(qiáng)大，研發(fā)團(tuán)隊(duì)擁有二十多年的行業(yè)技術(shù)經(jīng)驗(yàn)，能提供多樣化的PSRAM存儲(chǔ)產(chǎn)品?，F(xiàn)已發(fā)展成為PSRAM的龍頭廠商。主要研發(fā)部門位于日本，美國(guó)和大中華地區(qū)，銷售地點(diǎn)遍布全球。
存儲(chǔ)器PSRAM(pseudo SRAM)，稱之為偽靜態(tài)隨機(jī)存取器。它具有SRAM的接口協(xié)議：給出地址、讀寫指令，就可以實(shí)現(xiàn)數(shù)據(jù)的存??；相比DRAM的實(shí)現(xiàn)，它不需要復(fù)雜的memory controller來(lái)控制內(nèi)存單元去定期刷新數(shù)據(jù)，但是它的內(nèi)核架構(gòu)卻是DRAM架構(gòu)；傳統(tǒng)的SRAM是由6個(gè)晶體管構(gòu)成一個(gè)存儲(chǔ)cell，而psram則是由1個(gè)晶體管+一個(gè)電容構(gòu)成一個(gè)存儲(chǔ)cell，因此psram可以實(shí)現(xiàn)較大的存儲(chǔ)容量；
基于上述分析，新出現(xiàn)的存儲(chǔ)器psram相比傳統(tǒng)存儲(chǔ)器具有如下優(yōu)點(diǎn)：
1. 更大的帶寬：串行psram通過(guò)八路串行接口對(duì)外互聯(lián)，最高在200MHz Double-Data-Rate速率下，可實(shí)現(xiàn)超3Gbps的帶寬傳輸；
2. 更高的容量：目前可實(shí)現(xiàn)存儲(chǔ)容量有：32M、64M、256M，這比市面上其他串行接口隨機(jī)
存儲(chǔ)器的容量要大很多；
3. 更低的成本：串行psram采用DRAM架構(gòu)，可以有效壓縮芯片體積，故串行psram生產(chǎn)成本接近DRAM成本；
4. 更小的尺寸：串行psram的低引腳數(shù)封裝與傳統(tǒng)的RAM存儲(chǔ)相比，具有尺寸更小、成本更低等優(yōu)勢(shì)；
5. 更廣的應(yīng)用：psram采用的是自行刷新（Self-Refresh），不需要刷新電路即能保存它內(nèi)部存儲(chǔ)的數(shù)據(jù)；而DRAM每隔一段時(shí)間，要刷新充電一次，否則內(nèi)部的數(shù)據(jù)即會(huì)消失，因此psram相比傳統(tǒng)RAM會(huì)有更廣的應(yīng)用；
PSRAM作為常用的一種外設(shè)存儲(chǔ)設(shè)備，所具有的優(yōu)點(diǎn)使其廣泛被應(yīng)用。
