Hello. Are there any options currently available for double port sram, including EF_SRAM (commercial SRAM) and sky130_sram?

The open source

sky130_sram_macros

library contains 3 dual port (1RW, 1R) sram macros.

sky130_sram_1kbyte_1rw1r_32x256_8
sky130_sram_1kbyte_1rw1r_8x1024_8
sky130_sram_2kbyte_1rw1r_32x512_8

I don’t know how well they’ve been characterized though.

Thank you. I'll check it out.

The EF_SRAM macros are all single port.

@Yonguk Sim I expect the EF_SRAM macros could be interleaved so they can effectively be made to behave like a dual-port array. They can operate with a clock of at least 100MHz.
