U62H256AS2K35LLDG1 - Brand New ZMD IC Chips
-
Description
The U62H256AS2K35LLDG1 is a static RAM manufactured using a CMOS process technology. It operates in two modes: Read - Standby and Write - Data Retention. The memory array is based on a 6-transistor cell. The circuit is activated by the falling edge of E, with address and control inputs opening simultaneously. The data inputs or outputs are active based on the information of W and G. In a Read cycle, the data outputs are activated by the falling edge of G. After the address change, the data outputs go High-Z until the new information is available. The Read cycle is finished by the falling edge of W or the rising edge of E. Data retention is guaranteed down to 2 V. The inputs, except for E, consist of NOR gates, eliminating the need for pull-up/pull-down resistors.
