CS81 Series

■ COMPILED CELLS

Compiled cells are macro cells which are automatically generated with the bit/word configuration specified. The

CS81 series has the following types of compiled cells. (Note that each macro is different in word/bit range

depending on the column type.)

1.

Clock synchronous single-port RAM (1 address : 1 RW)

• High density type/Partial write type

• High speed type

• Large scale partial write type

2.

Clock synchronous dual-port RAM (2 addresses : 1 RW, 1 R)

• High density type/Partial write type

3.

Clock synchronous register file (3 addresses : 1 W, 2 R)

4.

Clock synchronous register file (4 addresses : 2 W, 2 R)

5.

Clock synchronous ROM (1 addresses, 1 R)

6.

Clock synchronous delay line memory (2 addresses : 1 W, 1 R)
