GF180 SRAM 宏尺寸

SRAM 型号	容量	物理尺寸	备注
`sram64x8`	512 bits	431.86um × 232.88um	64 字 × 8 位
`sram128x8`	1,024 bits (1 Kbit)	431.86um × 268.88um	128 字 × 8 位
`sram256x8`	2,048 bits (2 Kbit)	431.86um × 340.88um	256 字 × 8 位
`sram512x8`	4,096 bits (4 Kbit)	431.86um × 484.88um	512 字 × 8 位

1000um × 1000um Die 理论可放置容量

SRAM 型号	单个容量	最多数量	总容量	面积使用率
`sram512x8`	4,096 bits	4 个 (2×2)	16,384 bits（约 2 KB）	约 83.8%
`sram256x8`	2,048 bits	4 个 (2×2)	8,192 bits（约 1 KB）	约 52.4%
`sram128x8`	1,024 bits	6 个 (2×3)	6,144 bits（约 0.75 KB）	约 44.5%
`sram64x8`	512 bits	8 个 (2×4)	4,096 bits（约 0.5 KB）	约 40.7%

设计含义: 对 LSTM 权重 SRAM 估算时，1000um × 1000um die 中可用 SRAM 不应按裸宏理论上限直接规划。 Pad ring、电源网络、布线通道、MPO 留孔和 SRAM 间距都会进一步压缩可用容量。

所有标准单元尺寸与 1000um × 1000um 面积占比

下表从本地 GF180 PDK 标准单元 LEF 的 MACRO / SIZE 语句自动整理。面积占比基准为 1,000,000um²；例如 0.010000% 表示该单元面积约占 1000um × 1000um die 的万分之一。
