E2D0035-39-21 ¡ Semiconductor ¡ Semiconductor MSM6684B 4,194,304-word x 1-bit Serial Register This version: MSM6684B Feb. 1999 Previous version: May. 1997 GENERAL DESCRIPTION MSM6684B is a serial register organized as 4,194,304 words x one bit, characterized by mediumspeed, low power consumption operation. This device has a built-in internal address generation circuit allowing continuous serial read/write operation by external clock input. Read/write operation causes the internal address to be incremented automatically by +1. External address input enables addressing in units of 1024 words. Furthermore, a refresh timer and a refresh address counter are installed, which makes an external refresh circuit unnecessary. In addition, this configuration allows lower power consumption.
