512Kx36 SRAM with 3.8 ns access
The Renesas M5M5V5636GP-16I#B0 is a high-speed synchronous SRAM organized as 512K words by 36 bits, with a 3.8 ns access time. This places it in the fast-cache or networking buffer class, where the 36-bit word width matches a 32-bit data bus plus parity or ECC lane without external muxing.
