[IC設計] SRAM 的分類,1 port、2 port、dual port、register file、

在 memory compiler 中

可以透過簡易的勾選創造出我們所需要的Sram和Rom的Hard macro file

其中在Sram中可以看到許多種類型

以 tsmc 28nm為例

sram可分為

1. Dual Port High Density Leakage Control SRAM 1M Sync

2. Single Port High Density Gen2 Leakage Control Register File 128k Sync

3. Single Port High Speed Leakage Control Register File 128K Sync

4. Single Port High Speed Leakage Control SRAM 1M Sync

5. Single Port Ultra High Density Gen2 Leakage Control SRAM 2M

6. Two Port High Density Leakage Control Register File 128K Sync

7. Two Port Ultra High Density Leakage Control Register File 128K Sync

其中最主要的區別為 Single port、Two port、Dual port

甚至有些是SRAM有些是Register File (速度最快)
