Description
The U62H256A is a static RAM manufactured using a CMOS proess technology with the following
operating modes: Read - Standby
Write - Data Retention
The memory array is based on a 6-transistor cell. The circuit is activated by the falling edge of E. The address and ontrol inputs open simultaneously. According to the information of W and G, the data inputs, or outputs, are active. In a Read cycle, the data outputs are activated by the alling edge of G, afterwards the data word will be available at the outputs DQ0-DQ7. After the address change, the data outputs go High-Z until the new information is available. The data outputs have
no preferred state. The Read cycle is finished by the falling edge of W, or by the rising edge of E, respectively.
Data retention is guaranteed down to 2 V. With the exception of E, all inputs consist of NOR gates, so that no pull-up/pull-down resistors are required.
